SN54LS393 DUAL DECADE COUNTER / DUAL 4-STAGE BINARY COUNTER

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 code or they can count in a biquinary sequence to provide a square wave (50% duty cycle) at the final output. Each half of the LS393 operates as a Mo.
