MC74HC245A
Octal 3-State Noninverting
Bus Transceiver
High−Performance Silicon−Gate CMOS
The MC74HC245A is identical in pinout to the LS245. The device
inputs are compatible with standard CMOS outputs; with pull−up
resistors, they are compatible with LSTTL outputs.
The HC245A 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.
Features
• Output Drive Capability: 15 LSTTL Loads
• Outputs Directly Interface to CMOS, NMOS, and TTL
• Operating Voltage Range: 2.0 to 6.0 V
• Low Input Current: 1 mA
• High Noise Immunity Characteristic of CMOS Devices
• In Compliance with the Requirements Defined by JEDEC Standard
No. 7 A
• Chip Complexity: 308 FETs or 77 Equivalent Gates
• NLV Prefix for Automotive and Other Applications Requiring
Unique Site and Control Change Requirements; AEC−Q100
Qualified and PPAP Capable
• These Devices are Pb−Free, Halogen Free and are RoHS Compliant
