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 pullup
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. Output Drive Capability: 15 LSTTL Loads Outputs Directly Interface to CMOS, NMOS, and TTL Operating V oltage Range: 2 to 6 V Low Input Current: 1 μA High Noise Immunity Characteristic of CMOS Devices In Compliance with the Requirements Defined by JEDEC Standard
No. 7A Chip Complexity: 308 FETs or 77 Equivalent Gates
