4LS293 Decade and 4-bit Binary Counter
The 74LS series of integrated circuits (ICs) was one of the most popular logic families of transistor-transistor logic (TTL) logic chips. 74LS series is a bipolar, low-power Schottky IC. 74LS293 monolithic counters contain four master-slave flip-flops and additional gating to provide a divide-by-two counter and a three-stage binary counter.
