Description

AW39204/AW39204A is a 4-bit non-inverting bidirectional voltage-level translator, it can be used to convert digital signal with mixed-voltage systems. It needs two separate power supply rails, with the A ports supporting operating voltages from 1.1 V to 5 V while it tracks the VCCA supply, and the B ports supporting operating voltages from 1.1 V to 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 1.2 V,1.8 V, 2.5 V, 3.3 V, and 5 V voltage nodes. If the voltage level of output-enable (OE) pin is low, the chip works in the high-impedance state, which significantly reduces the power-supply quiescent current consumption. And the OE input circuit is supplied by VCCA. To ensure the high-impedance state during power up or power down, OE should be tied to GND through a pull-down resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver.
