Synchronous Up/Down Counters with Down/Up Mode Control

The ‘190, ‘LS190, ‘191, and ‘LS191 are synchronous, reversible up/down counters having a

complexity of 58 equivalent gates. The ‘191 and ‘LS191 are 4-bit binary counters and the ‘190

and ‘LS190 are BCD counters. Synchronous operation is provided by having all ﬂip-ﬂops clocked

simultaneously so that the outputs change coincident 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.
