DESCRIPTION/ORDERING INFORMATION
This two-bit non-inverting translator is a bidirectional voltage-level translator and can be used to establish digital
switching compatibility between mixed-voltage systems. It uses two separate configurable power-supply rails,
with the A ports supporting operating voltages from 1.65 V to 3.6 V while it tracks the VCCA supply, and the B
ports supporting operating voltages from 2.3 V to 5.5 V while it tracks the VCCB supply. This allows the support of
both lower and higher logic signal levels while providing bidirectional translation capabilities between any of the
1.8-V, 2.5-V, 3.3-V, and 5-V voltage nodes.
When the output-enable (OE) input is low, all I/Os are placed in the high-impedance state, which significantly
reduces the power-supply quiescent current consumption.
To ensure the high-impedance state during power up or power down, OE should be tied to GND through a
pulldown resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver.

PRINCIPLES OF OPERATION
Applications
The TXS0102 can be used to bridge the digital-switching compatibility gap between two voltage nodes to
successfully interface logic threshold levels found in electronic systems. It should be used in a point-to-point
topology for interfacing devices or systems operating at different interface voltages with one another. Its primary
target application use is for interfacing with open-drain drivers on the data I/Os such as I2C or 1-wire, where the
data is bidirectional and no control signal is available. The TXS0102 can also be used in applications where a
push-pull driver is connected to the data I/Os, but the TXB0102 might be a better option for such push-pull
applications.
Architecture
The TXS0102 architecture (see Figure 1) is an auto-direction-sensing based translator that does not require a
direction-control signal to control the direction of data flow from A to B or from B to A.

Figure 1. Architecture of a TXS01xx Cell
These two bidirectional channels independently determine the direction of data flow without a direction-control
signal. Each I/O pin can be automatically reconfigured as either an input or an output, which is how this
auto-direction feature is realized.
The TXS0102 is part of TI's "Switch" type voltage translator family and employs two key circuits to enable this
voltage translation:
1) An N-channel pass-gate transistor topology that ties the A-port to the B-port
and
2) Output one-shot (O.S.) edge-rate accelerator circuitry to detect and accelerate rising edges on the A or B
ports
For bidirectional voltage translation, pull-up resistors are included on the device for dc current sourcing capability.
The VGATE gate bias of the N-channel pass transistor is set at approximately one threshold voltage (VT) above
the VCC level of the low-voltage side. Data can flow in either direction without guidance from a control signal.
The O.S. rising-edge rate accelerator circuitry speeds up the output slew rate by monitoring the input edge for
transitions, helping maintain the data rate through the device. During a low-to-high signal rising edge, the O.S.
circuits turn on the PMOS transistors (T1, T2) to increase the current drive capability of the driver for
approximately 30 ns or 95% of the input edge, whichever occurs first. This edge-rate acceleration provides high
ac drive by bypassing the internal 10-kΩ pull-up resistors during the low-to-high transition to speed up the signal.
The output resistance of the driver is decreased to approximately 50 Ω to 70 Ω during this acceleration phase. To
minimize dynamic ICC and the possibility of signal contention, the user should wait for the O.S. circuit to turn-off
before applying a signal in the opposite direction. The worst-case duration is equal to the minimum pulse-width
number provided in the Timing Requirements section of this data sheet.

Input Driver Requirements
The continuous dc-current "sinking" capability is determined by the external system-level open-drain (or
push-pull) drivers that are interfaced to the TXS0102 I/O pins. Since the high bandwidth of these bidirectional I/O
circuits is used to facilitate this fast change from an input to an output and an output to an input, they have a
modest dc-current "sourcing" capability of hundreds of micro-Amps, as determined by the internal 10-kΩ pullup
resistors.
The fall time (tfA, tfB) of a signal depends on the edge-rate and output impedance of the external device driving
TXS0102 data I/Os, as well as the capacitive loading on the data lines.
Similarly, the tPHL and max data rates also depend on the output impedance of the external driver. The values for
tfA, tfB, tPHL, and maximum data rates in the data sheet assume that the output impedance of the external driver is
less than 50 Ω.
Output Load Considerations
TI recommends careful PCB layout practices with short PCB trace lengths to avoid excessive capacitive loading
and to ensure that proper O.S. triggering takes place. PCB signal trace-lengths should be kept short enough
such that the round trip delay of any reflection is less than the one-shot duration. This improves signal integrity
by ensuring that any reflection sees a low impedance at the driver. The O.S. circuits have been designed to stay
on for approximately 30 ns. The maximum capacitance of the lumped load that can be driven also depends
directly on the one-shot duration. With very heavy capacitive loads, the one-shot can time-out before the signal is
driven fully to the positive rail. The O.S. duration has been set to best optimize trade-offs between dynamic ICC
,
load driving capability, and maximum bit-rate considerations. Both PCB trace length and connectors add to the
capacitance that the TXS0102 output sees, so it is recommended that this lumped-load capacitance be
considered to avoid O.S. retriggering, bus contention, output signal oscillations, or other adverse system-level
affects.
Power Up
During operation, ensure that VCCA ≤ VCCB at all times. The sequencing of each power supply will not damage
the device during the power up operation, so either power supply can be ramped up first.
Enable and Disable
The TXS0102 has an OE input that is used to disable the device by setting OE low, which places all I/Os in the
Hi-Z state. The disable time (tdis) indicates the delay between the time when OE goes low and when the outputs
are disabled (Hi-Z). The enable time (ten) indicates the amount of time the user must allow for the one-shot
circuitry to become operational after OE is taken high.
Pullup or Pulldown Resistors on I/O Lines
Each A-port I/O has an internal 10-kΩ pullup resistor to VCCA, and each B-port I/O has an internal 10-kΩ pullup
resistor to VCCB. If a smaller value of pullup resistor is required, an external resistor must be added from the I/O
to VCCA or VCCB (in parallel with the internal 10-kΩ resistors). Adding lower value pull-up resistors will effect VOL
levels, however. The internal pull-ups of the TXS0102 are disabled when the OE pin is low.
