MC74HC245AF

Manufacturer Part Number
MC74HC245AF
Description
Octal 3-State Noninverting Bus Transceiver
Manufacturer
ONSEMI [ON Semiconductor]
Datasheet
MC74HC245A
Octal 3−State Noninverting
Bus Transceiver
High−Performance Silicon−Gate CMOS
inputs are compatible with standard CMOS outputs; with pull−up
resistors, they are compatible with LSTTL outputs.
2−way asynchronous communication between data buses. The device
has an active−low Output Enable pin, which is used to place the I/O
ports into high−impedance states. The Direction control determines
whether data flows from A to B or from B to A.
