MC74HC254A Datasheet | Motorola Semiconductor

MOTOROLA SEMICONDUCTOR TECHNICAL DATA Octal 3-State Noninverting Bus Transceiver High- Performance Silicon- Gate CMOS The MC54/74HC245A is identical in pinout to the LS245. The device inputs are patible with standard CMOS outputs; with pullup resistors, they are patible with LSTTL outputs. The HC245A is a 3- state noninverting transceiver that is used for 2- way asynchronous munication 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. - - - - - - Output Drive Capability: 15 LSTTL Loads Outputs Directly Interface to CMOS,...
