(1) Operation outside the Absolute Maximum Ratings may cause permanent device damage. Absolute Maximum Ratings do not imply  
functional operation of the device at these or any other conditions beyond those listed under Recommended Operating Conditions.. If  
used outside the Recommended Operating Conditions but within the Absolute Maximum Ratings, the device may not be fully  
functional, and this may affect device reliability, functionality, performance, and shorten the device lifetime.  
(2) The input voltage and output negative-voltage ratings may be exceeded if the input and output current ratings are observed.  
(3) The output positive-voltage rating may be exceeded up to 6.5 V maximum if the output current rating is observed.

8 Detailed Description  
8.1 Overview  
The TXU0101-Q1 is a 4-bit translating transceiver that uses two individually configurable power-supply rails. The  
device is operational with VCCA and VCCB supplies as low as 1.1 V and as high as 5.5 V. Additionally, the device  
can be operated with VCCA = VCCB. The A port is designed to track VCCA, and the B port is designed to track  
VCCB  
.
The TXU0101-Q1 device is designed for asynchronous communication between data buses, and transmits data  
with fixed direction from the A bus to the B bus on some channels and from the B bus to the A bus on the  
remaining channels. The output-enable input (OE) is used to disable the outputs so the buses are effectively  
isolated. The output-enable pin of the TXU0101-Q1 (OE) can be referenced to either VCCA or VCCB. The OE pin  
can be left floating or externally pulled down to ground to ensure the high-impedance state of the level shifter  
outputs during power up or power down.  
This device is fully specified for partial-power-down applications using the Ioff current. The Ioff protection circuitry  
ensures that no excessive current is drawn from or sourced into an input or output while the device is powered  
down.  
The VCC isolation or VCC disconnect feature ensures that if either VCC is less than 100 mV or disconnected  
with the complementary supply within recommended operating conditions, then the outputs disable and are set  
to the high-impedance state while the supply current is maintained. The Ioff-float circuitry ensures that no  
excessive current is drawn from or sourced into an input or output while the supply is floating.  
Glitch-free power supply sequencing allows either supply rail to be powered on or off in any order while providing  
robust power sequencing performance.

8.3 Feature Description  
8.3.1 CMOS Schmitt-Trigger Inputs with Integrated Pulldowns  
Standard CMOS inputs are high impedance and are typically modeled as a resistor in parallel with the input  
capacitance given in the Electrical Characteristics. The worst case resistance is calculated with the maximum  
input voltage, given in the Absolute Maximum Ratings, and the maximum input leakage current, given in the  
Electrical Characteristics, using ohm's law (R = V ÷ I).  
The Schmitt-trigger input architecture provides hysteresis as defined by ΔVT in the Electrical Characteristics,  
which makes this device extremely tolerant to slow or noisy inputs. Driving the inputs slowly will increase  
dynamic current consumption of the device. See Understanding Schmitt Triggers for additional information  
regarding Schmitt-trigger inputs.  
8.3.1.1 Inputs with Integrated Static Pull-Down Resistors  
This device has 5 MΩ typical integrated weak pull-downs for each input. This feature allows all inputs to be left  
floating without the concern for unstable outputs or increased current consumption. This also helps to reduce  
external component count for applications where not all channels are used or need to be fixed low. If an external  
pull-up is required, it should be no larger than 1 MΩto avoid contention with the 5 MΩinternal pull-down.  
8.3.2 Control Logic (OE) with VCC(MIN) Circuitry  
The output-enable input (OE) is used to disable the outputs so the buses are effectively isolated. The output-  
enable pin of the TXU0x04 has VCC(MIN) circuitry, which allows the OE pin to operate with the lower supply  
voltage. The Over-Voltage Tolerant Inputs feature allows the OE pin to operate with the higher supply voltage.  
This combination means that the enable pin can be referenced to either VCCA or VCCB supply. Multiple  
permutations of each device are possible since the controller can be placed on either the A or B port and can still  
control the enable pin.  
8.3.3 Balanced High-Drive CMOS Push-Pull Outputs  
A balanced output allows the device to sink and source similar currents. The high drive capability of this device  
creates fast edges into light loads, so routing and load conditions should be considered to prevent ringing.  
Additionally, the outputs of this device are capable of driving larger currents than the device can sustain without  
being damaged. The electrical and thermal limits that must be followed at all times are defined in Absolute  
Maximum Ratings.  
8.3.4 VCC Isolation and VCC Disconnect  
The outputs for this device disable and enter a high-impedance state when either supply is <100 mV or left  
floating (disconnected), with the complementary supply within the recommended operating conditions. It is  
recommended to keep the inputs low before floating (disconnecting) either supply.  
The ICCx(floating) in the Electrical Characteristics specifies the maximum supply current. The Ioff(float) in the  
Electrical Characteristics specifies the maximum leakage into or out of any input or output pin on the device.

8.3.5 Over-Voltage Tolerant Inputs  
Input signals to this device can be driven above the supply voltage as long as they remain below the maximum  
input voltage value specified in the Recommended Operating Conditions.  
8.3.6 Glitch-Free Power Supply Sequencing  
Either supply rail may be powered on or off in any order without producing a glitch on the inputs or outputs (that  
is, where the output erroneously transitions to VCC when it should be held low or vice versa). Glitches of this  
nature can be misinterpreted by a peripheral as a valid data bit, which could trigger a false device reset of the  
peripheral, a false device configuration of the peripheral, or even a false data initialization by the peripheral.

11 Layout  
11.1 Layout Guidelines  
To ensure reliability of the device, following common printed-circuit board layout guidelines is recommended:  
Use bypass capacitors on the power supply pins and place them as close to the device as possible. A 0.1 µF  
capacitor is recommended, but transient performance can be improved by having 1 µF and 0.1 µF capacitors  
in parallel as bypass capacitors.  
The high drive capability of this device creates fast edges into light loads so routing and load conditions  
should be considered to prevent ringing.

(1) The marketing status values are defined as follows:  
ACTIVE: Product device recommended for new designs.  
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.  
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.  
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.  
OBSOLETE: TI has discontinued the production of the device.  
(2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance  
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may  
reference these types of products as "Pb-Free".  
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.  
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based  
flame retardants must also meet the <=1000ppm threshold requirement.  
(3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.  
(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.  
(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation  
of the previous line and the two combined represent the entire Device Marking for that device.  
(6)  
Lead finish/Ball material - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead finish/Ball material values may wrap to two  
lines if the finish value exceeds the maximum column width.
