3 Description

This 4-bit non-inverting translator uses two separate

configurable power-supply rails. The A port is

designed to track VCCA. VCCA accepts any supply

voltage from 1.65 V to 3.6 V. VCCA must be less

than or equal to VCCB. The B port is designed to

track VCCB. VCCB accepts any supply voltage from 2.3

V to 5.5 V. This allows for low-voltage bidirectional

translation 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 outputs

are placed in the high-impedance state.

The TXS0104E is designed so that the OE input

circuit is supplied by VCCA.

For the high-impedance state during power up

or power down, tie OE to GND through a pulldown

resistor; the minimum value of the resistor is

determined by the current-sourcing capability of the

driver.
