74F656A
Octal buffer/driver with parity; non-inverting; 3-state
Rev. 05 — 25 March 2010
Product data sheet
1. General description
The 74F656A is an octal buffer and line driver with parity generation/checking. The
74F656A can be used as memory address driver, clock driver and bus-oriented
transmitter/receiver. The inclusion of parity generation/checking improves PCB density.
2. Features
Combines 74F244 and 74F280A functions in one device
High impedance NPN base inputs for reduced input current (40
μA
in HIGH and LOW
states)
I
IL
= 20
μA
compared to 600
μA
in FAST family specification
For applications with high output drive and light bus loading
Non-inverting
3-state output sink capability I
OL
= 64 mA and source I
OH
