说明

This 4-bit noninverting bus transceiver uses two separate configurable power-supply rails to enable asynchronous communication between B-port inputs and A-port outputs. The A port is designed to track V_CCA while the B port is designed to track V_CCB. Both V_CCA and V_CCB are configurable from 0.9 V to 3.6 V.

The SN74AVC4T234 solution offers the industry's low-power needs in battery-powered portable applications by ensuring both a very low static and dynamic power consumption across the entire V_CC range of 0.9 V to 3.6 V, resulting in an increased battery life. This product also maintains excellent signal integrity.

This device is fully specified for partial-power-down applications using I_off. The I_off circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
