description/ordering information
The
鈥橦C193
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.
