Dual 4??tage Binary Counter

The SN74LS393 contains a pair of high-speed 4-stage ripple counters. Each half of the LS393 operates as a Modulo-16 binary divider, with the last three stages triggered in a ripple fashion. In the LS393, the flip-flops are triggered by a HIGH-to-LOW transition of their CP inputs. Each half of eac

Each of these monolithic circuits contains eight master-slave flip-flops and additional gating to implement two individual four-bit counters in a single package. The '390 and 'LS390 incorporate dual divide-by-two and divide-by-five counters, which can be used to implement cycle lengths equal to any ? Dual Versions of the Popular '90A, 'LS90 and '93A, 'LS93? '390, 'LS390 … Individual Clocks for A and B Flip-Flops Provide Dual ÷ 2 and ÷ 5 Counters? '393, 'LS393 … Dual 4-Bit Binary Counter with Individual Clocks? All Have Direct Clear for Each 4-Bit Counter? Dual 4-Bit Versions Can Significantly ;
