SEMICONDUCTOR TECHNICAL DATA
Octal 3-State Noninverting Bus Transceiver with LSTTL Compatible Inputs
High–Performance Silicon–Gate CMOS
The MC54/74HCT245A 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 MC54/74HCT245A 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. • • • • • • Output Drive Capability: 15 LSTTL Loads TTL/NMOS Compatible Input Levels Outputs Directly Interface to CMOS, NMOS and TTL Operating Voltage Range: 4.5 to 5.
