FEATURES  
DESCRIPTION  
This 4-bit non-inverting translator uses two separate  
configurable power-supply rails. The port is  
•
Fully Symmetric Supply Voltages. 0.9 V to 3.6  
V on A Port and 0.9 V to 3.6 V  
A
•
VCC Isolation Feature – If Either VCC Input Is at  
GND, All Outputs Are in the High-Impedance  
State  
designed to track VCCA. VCCA accepts any supply  
voltage from 0.9 V to 3.6 V. The B port is designed to  
track VCCB. VCCB accepts any supply voltage from 0.9  
V to 3.6 V. This allows for low-voltage bidirectional  
translation between 1-V, 1.2-V, 1.5-V, 1.8-V, 2.5-V  
and 3.3-V voltage nodes. For the TXB0304, 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  
TXB0304 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.

A. Pull up resistors are not required on both sides for Logic I/O.  
B. If pull up or pull down resistors are needed, the resistor value must be over 20 kΩ.  
C. 20 kΩ is a safe recommended value, if the customer can accept higher Vol or lower Voh, smaller pull up or pull down  
resistor is allowed, the draft estimation is Vol = Vccout × 1.5k/(1.5k + Rpu) and Voh = Vccout × Rdw/(1.5k + Rdw).  
D. If pull up resistors are needed, please refer to the TXS0104 or contact TI.  
E. For detailed information, please refer to application note SCEA043.
