Up/down binary counter with reset and ripple clock

DESCRIPTION The 74F191 is a 4-bit binary counter. It contains four edge-triggered master/slave flip-flops with internal gating and steering logic to provide asynchronous preset and synchronous count-up and count-down operations. FEATURES • High speed –125MHz typical fMAX • Synchronous, reversi
