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.
● Wide Operating VCC Range of 0.9 V to 3.6 V
● 3.6-V I/O Tolerant to Support Mixed-Mode Signal Operation
● Max tpd of 3.7 ns at 3.3 V
