MC74HCT245AN

八路三态同相总线收发器与LSTTL兼容输入 Octal 3−State Noninverting Bus Transceiver with LSTTL Compatible Inputs

Octal 3−State Noninverting Bus Transceiver with LSTTL Compatible Inputs

High−Performance Silicon−Gate CMOS

The MC74HCT245A is identical in pinout to the LS245. This device may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. The MC74HCT245A 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.
