DESCRIPTION/ORDERING INFORMATION  
This 4-bit noninverting translator uses two separate configurable power-supply rails. The A port is designed to  
track VCCA. VCCA accepts any supply voltage from 1.2 V to 3.6 V. The B port is designed to track VCCB. VCCB  
accepts any supply voltage from 1.65 V to 5.5 V. This allows for universal low-voltage bidirectional translation  
between any of the 1.2-V, 1.5-V, 1.8-V, 2.5-V, 3.3-V, and 5-V voltage nodes. VCCA should not exceed VCCB  
.
When the output-enable (OE) input is low, all outputs are placed in the high-impedance state. 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.  
The TXB0104 is designed so that the OE input circuit is supplied by VCCA  
.
This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs,  
preventing damaging current backflow through the device when it is powered down.

PRINCIPLES OF OPERATION  
Applications  
The TXB0104 can be used in level-translation applications for interfacing devices or systems operating at  
different interface voltages with one another.  
Architecture  
The TXB0104 architecture (see Figure 1) does not require a direction-control signal to control the direction of  
data flow from A to B or from B to A. In a dc state, the output drivers of the TXB0104 can maintain a high or low,  
but are designed to be weak, so that they can be overdriven by an external driver when data on the bus starts  
flowing the opposite direction.  
The output one shots detect rising or falling edges on the A or B ports. During a rising edge, the one shot turns  
on the PMOS transistors (T1, T3) for a short duration, which speeds up the low-to-high transition. Similarly,  
during a falling edge, the one shot turns on the NMOS transistors (T2, T4) for a short duration, which speeds up  
the high-to-low transition. The typical output impedance during output transition is 70 Ω at VCCO = 1.2 V to 1.8 V,  
50 Ω at VCCO = 1.8 V to 3.3 V, and 40 Ω at VCCO = 3.3 V to 5 V.

Input Driver Requirements  
Typical IIN vs VIN characteristics of the TXB0104 are shown in Figure 2. For proper operation, the device driving  
the data I/Os of the TXB0104 must have drive strength of at least ±2 mA.

Figure 2. Typical IIN vs VIN Curve  
Power Up  
During operation, ensure that VCCA ≤ VCCB at all times. During power-up sequencing, VCCA ≥ VCCB does not  
damage the device, so any power supply can be ramped up first. The TXB0104 has circuitry that disables all  
output ports when either VCC is switched off (VCCA/B = 0 V).  
Enable and Disable  
The TXB0104 has an OE input that is used to disable the device by setting OE = low, which places all I/Os in the  
high-impedance (Hi-Z) state. The disable time (tdis) indicates the delay between when OE goes low and when the  
outputs actually 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  
The TXB0104 is designed to drive capacitive loads of up to 70 pF. The output drivers of the TXB0104 have low  
dc drive strength. If pullup or pulldown resistors are connected externally to the data I/Os, their values must be  
kept higher than 50 kΩ to ensure that they do not contend with the output drivers of the TXB0104.  
For the same reason, the TXB0104 should not be used in applications such as I2C or 1-Wire where an  
open-drain driver is connected on the bidirectional data I/O. For these applications, use a device from the TI  
TXS01xx series of level translators.
