MC74HC640A
Octal 3-State Inverting Bus Transceiver
SEMICONDUCTOR TECHNICAL DATA -
High–Performance Silicon–Gate CMOSThe MC54/74HC640A is identical in pinout to the LS640. The device
inputs are compatible with standard CMOS outputs; with pullup resistors,
they are compatible with LSTTL outputs.
The HC640A is a 3–state 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 Voltage 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: 276 FETs or 69 Equivalent Gates
