SN74LXCH8T245 8-Bit Bus Transceiver

Texas Instruments SN74LXCH8T245 8-Bit Bus Transceiver is a dual-supply non-inverting bidirectional voltage level translation device with bus-hold circuitry. Ax pins and control pins (DIR and OE) are referenced to V_CCA logic levels, and Bx pins are referenced to V_CCB logic levels. The A port can accept I/O voltages ranging from 1.1V to 5.5V, while the B port can accept I/O voltages from 1.1V to 5.5V. A high on DIR allows data transmission from A to B, and a low on DIR allows data transmission from B to A when OE is set to low. When the Texas Instruments SN74LXCH8T245 OE is set to high, both Ax and Bx pins are in the high-impedance state.
