SN74AXCH2T45 Dual-Supply Bus Transceiver
Texas Instruments SN74AXCH2T45 Dual-Supply Bus Transceiver is a two-bit, non-inverting bus transceiver that uses two individually configurable power-supply rails. The device is operational with VCCA and VCCB supplies as low as 0.65V. The A port is designed to track VCCA, which accepts any supply voltage from 0.65V to 3.6V. The B port is designed to track VCCB, which also accepts any supply voltage from 0.65V to 3.6V. The SN74AXCH2T45 is also compatible with a single-supply system. The Texas Instruments SN74AXCH2T45 is designed for asynchronous communication between data buses. The device 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 input (DIR). The SN74AXCH2T45 is designed to reference the control pin (DIR) to VCCA.
