description/ordering information

The ’HC193 devices are 4-bit synchronous, reversible, up/down binary counters.

Synchronous operation is provided by having all flip-flops clocked simultaneously so that the outputs change

coincidentally with each other when so instructed by the steering logic. This mode of operation eliminates the

output counting spikes normally associated with asynchronous (ripple-clock) counters.

SCLS122D − DECEMBER 1982 − REVISED OCTOBER 2003 description/ordering information (continued) The outputs of the four flip-flops are triggered on a low-to-high-level transition of either count (clock) input (UP or DOWN). The direction of counting is determined by which count input is pulsed while the other count input is high.
