SN74LVC245APWLE

八路总线收发器与3态输出 OCTAL BUS TRANSCEIVER WITH 3-STATE OUTPUTS

DESCRIPON/ORDERING INFORMATION

This octal bus transceiver is designed for 1.65-V to 3.6-V VCC operation. The SN74LVC245A 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 at the direction-control DIR input.
