74F579
8-Bit Bidirectional Binary Counter with 3-STATE Outputs
General Description
The 74F579 is a fully synchronous 8-stage up/down
counter with multiplexed 3-STATE I/O ports for bus-ori-
ented applications. It features a preset capability for pro-
grammable operation, carry lookahead for easy cascading
and a U/D input to control the direction of counting. All state
changes, whether in counting or parallel loading, are initi-
ated by the rising edge of the clock.
