Description

The 74F579 is a fully synchronous 8-stage up/down counter with multiplexed 3-STATE I/O ports for bus-oriented applications. It features a preset capability for programmable operation, carry lookahead for easy cascading and a U/D input to control the direction of counting. All state of the 74F579 changes, whether in counting or parallel loading, are initiated by the rising edge of the clock.
