SN74AXCH4T245 4-Bit Bus Transceiver

Texas Instruments SN74AXCH4T245 4-Bit Bus Transceiver uses two individually configurable power-supply rails. The device is operational with V_CCA and V_CCB supplies as low as 0.65V. The A port is designed to track V_CCA, which accepts any supply voltage from 0.65V to 3.6V. The B port is designed to track V_CCB, which accepts any supply voltage from 0.65V to 3.6V. The Texas Instruments SN74AXCH4T245 is compatible with a single-supply system. The device is designed for asynchronous communication between data buses. It transmits data from the A bus to the B bus or from the B bus to the A bus, depending on the logic level of the direction-control inputs (1DIR and 2DIR). The output-enable inputs (1OE and 2OE) disable the outputs so the buses are effectively isolated. All control pins (xDIR and xOE) are referenced to V_CCA.
