8-BIT BIDIRECTIONAL

BINARY COUNTER (3-STATE)

The MC74F579 is a fully synchronous 8-stage up/down counter with multi-

plexed 3-state I/O ports for bus-oriented applications. It features a preset

capability for programmable operation, carry look-ahead for easy cascading

and a U/D input to control the direction of counting. All state changes, except

forthecaseofasynchronousreset, areinitiatedbytherisingedgeoftheclock.

TC output is not recommended for use as a clock or asynchronous reset due

to the possibility of decoding spikes.
