1. Description

This device is an 8-bit non-inverting level translatorthat uses two separate configurable power-supplyrails. The A port tracks the VccA pin supply voltage.The VccA pin accepts any supply voltage between 1.4V and 3.6 V. The B port tracks the Vccb pin supplyvoltage. The VccB pin accepts any supply voltagebetween 1.65 V and 5.5 V. Two input supply pinsallows for low Voltage bidirectional translationbetween any of the 1.5 V, 1.8 V, 2.5 V 3.3 V, and 5V voltage nodes When the output-enable (OE) input is low, all outputsare placed in the high-impedance (Hi-2) state.To ensure the Hi-Z state during power-up or power-down periods, tie OE to GND through a pull-downresistor. The minimum value of the resistor isdetermined by the current-sourcing capability of thedriver.
