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 V_CCA while the B port is designed to track V_CCB. Both V_CCA and V_CCB are configurable from 0.9V to 3.6V. TI SN74AVC4T234 4-Bit Non-Inverting Bus Translator ensures both a very low static and dynamic power consumption across the entire V_CC range of 0.9V to 3.6V, resulting in an increased battery life. The TI SN74AVC4T234 Dual-Supply Bus Transceiver also maintains excellent signal integrity and is fully specified for partial-power-down applications using I_off.
