Motorola => Freescale
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 µA
• In Compliance with the Requirements Defined by JEDEC Standard No. 7A
• Chip Complexity: 304 FETs or 76 Equivalent Gates
