General 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 changes, whether in counting or parallel loading, are initiated by the rising edge of the clock.
●Features
●■ Multiplexed 3-STATE I/O ports
●■ Built-in lookahead carry capability
●■ Count frequency 100 MHz typical
●■ Supply current 75 mA typical
●■ Guaranteed 4000V minimum ESD protection
