74HC393 Datasheet (Texas Instruments) - Dual 4-Stage Binary Counter

74HC393, Dual 4-Stage Binary Counter

ordering information The ’HC393 devices contain eight flip-flops and additional gating to implement two individual 4-bit counters in a single package.

These devices comprise two independent 4-bit binary counters, each having a clear (CLR) and a clock (CLK) input.

N-bit binary counters can be impleme
