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 5.5 V
Low Input Current: 1.0
