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 VCCA while the B port is designed to track VCCB. Both VCCA and VCCB 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 VCC 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 Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
The VCC isolation feature ensures that if either VCC input is at GND, then A-side ports are in the high-impedance state.
