双路 4 位二进制计数器

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\n• '390, 'LS390 … Individual Clocks for A and B Flip-Flops Provide Dual ÷ 2 and ÷ 5 Counters\n• '393, 'LS393 … Dual 4-Bit Binary Counter with Individual Clocks\n• All Have Direct Clear for Each 4-Bit Counter\n• Dual 4-Bit Versions Can Signif;

DUAL DECADE COUNTER; DUAL 4-STAGE BINARY COUNTER

The SN54/74LS390 and SN54/74LS393 each contain a pair of high-speed 4-stage ripple counters. Each half of the LS390 is partitioned into a divide-by-two section and a divide-by five section, with a separate clock input for each section. The two sections can be connected to count in the 8.4.2.1 BCD
