SN74HC393/SN74HCS393 Dual 4-Bit Binary Counters

Texas Instruments SN74HC393/SN74HCS393 Dual 4-Bit Binary Counters 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 implemented with each package, providing the capability of dividing by 256. The Texas Instruments SN74HC393/SN74HCS393 have parallel outputs from each counter stage so that any submultiple of the input count frequency is available for system timing signals.
