74HCT245
Octal 3-State Noninverting
Bus Transceiver with
LSTTL-Compatible Inputs
High-Performance Silicon-Gate CMOS
The 74HCT245 is identical in pinout to LS245. The device has
TTL-Compatible Inputs.
The HCT245 is a 3-state noninverting transceiver that is used for
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.
