Description

This 4-bit non-inverting translator uses two separate configurable power-supply rails. The A port is designed to track V CCA . V CCA accepts any supply voltage from 1.65 V to 3.6 V. V CCA
must be less than or equal to V CCB . The B port is designed to track V CCB . V CCB 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.

Features

1. No Direction-Control Signal Needed

2. 1.65 V to 3.6 V on A port and 2.3 V to 5.5 V on B port (VCCA ≤ VCCB)

3. No Power-Supply Sequencing Required – VCCA or VCCB Can Be Ramped First

4. Latch-Up Performance Exceeds 100 mA Per JESD 78, Class II
