MC74HC245A
Octal 3State Noninverting
Bus Transceiver
HighPerformance SiliconGate CMOS
The MC74HC245A is identical in pinout to the LS245. The device
inputs are compatible with standard CMOS outputs; with pullup
resistors, they are compatible with LSTTL outputs.
The HC245A is a 3state noninverting transceiver that is used for
2way asynchronous communication between data buses. The device
has an activelow Output Enable pin, which is used to place the I/O
ports into highimpedance 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 A
High Noise Immunity Characteristic of CMOS Devices
In Compliance with the Requirements Defined by JEDEC Standard
No. 7A
Moisture Sensitivity: MSL1 for All Packages
Chip Complexity: 308 FETs or 77 Equivalent Gates
PbFree Packages are Available*
