Texas Instruments SN74AVC4T234 4-Bit Dual-Supply Bus Transceiver
Texas Instruments SN74AVC4T234 4-Bit Dual-Supply Bus Transceiver uses two separate configurable power-supply rails to enable asynchronous communication between B-port inputs and A-port inputs. The A port is designed to track VCCA, while the B port is designed to track VCCB. Both VCCA and VCCB are configurable from 0.9V to 3.6V. SN74AVC4T234 ensures both a very low static and dynamic power consumption across the entire VCC range of 0.9V to 3.6V, resulting in increased battery life. The Texas Instruments SN74AVC4T234 Dual-Supply Bus Transceiver also maintains excellent signal integrity and is fully specified for partial-power-down applications using Ioff.
