AW39102 is a 2-bit high-performance voltage-level translator without direction control signal, which is a non-inverting converter and can be used to convert digital signal with mixed-voltage systems. It needs two separate power supply rails, with the A ports tracks the VCCA ranging from 1.65 V to 3.6 V, and the B ports tracks the VCCB ranging from 2.3 V to 5.5 V. This makes the chip has capabilities of support both lower and higher logic signal levels translation between any of the 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 costs ultra-low power-supply quiescent current. And the OE input circuit is supplied by VCCA. Meanwhile, OE is recommended to be tied to GND through a pull-down resistor to ensure the high-impedance state during power up or power down.
When A/B ports operating in high-impedance state, the A/B Ports should be pull-down/high through resisters to ensure the A/B Ports having fixed state.
No power supply sequencing requirements means either VCCA or VCCB can be powered up first, and OE should be enabled after both VCCA and VCCB are established.
