Presettable synchronous 4-bit binary up/down counter

The 74HC191 is an asynchronously presettable 4-bit binary up/down counter. It contains four master/slave flip-flops with internal gating and steering logic to provide asynchronous preset and synchronous count-up and count-down operation. Asynchronous parallel load capability permits the counter to b • Complies with JEDEC standard no. 7A\n• CMOS input levels\n• Synchronous reversible counting\n• Asynchronous parallel load\n• Count enable control for synchronous expansion\n• Single up/down control input\n• ESD protection:• HBM JESD22-A114F exceeds 2000 V\n• MM JESD22-A115-A exceeds 200 V\n\n• Spe;
