Description

The SN74HC191DR devices are 4-bit synchronous,reversible,up/down binary counters.Synchronous counting operation is provided by having all flip-flops clocked simultaneously so that the outputs change coincident with each other when instructed by the steering logic. This mode of operation eliminates the output counting spikes normally associated with asynchronous(ripple-clock) counters. SN74HC191DR Features • Wide Operating Voltage Range of 2 V to 6 V• Outputs Can Drive Up To 10 LSTTL Loads• Low Power Consumption, 80-µA Max ICC• Typical tpd = 13 ns• ±4-mA Output Drive at 5 V• Low Input Current of 1 µA Max• Single Down/Up Count-Control Line
