Product Description

*-bit bidirectional voltage-level translator.This *-bit non-inverting translort is bidrectional valtage-level voltage-level translator and can be used to establish digital switching compatibility between mixed-voltage systems. It uses two separate configurable powersupply rails, with the A ports supporting operating voltages from 1.*5 V to 3.6 V while it tracks the VCCA supply, and the B ports supporting operating voltages from 2.3 V to 5.5 V while it tracks the VCCB supply. This allows the support of both lower and higher logic signal levels while providing bidirectional translation capabilities between any of the 1.*-V, 2.*-V, 3.*-V, and *-V voltage nodes. When the output-enable (OE) is low, all I/Os are placed in the high-impedance state, which significantly reduces the power-supply quiescent current consumption. 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.
