open-in-new Find other Counter, arithmetic & parity function ICs

Description

The SN74LV393A contains eight flip-flops and additional gating to implement two individual 4-bit counters in a single package. This device is designed for 2-V to 5.5-V VCC operation.

This device comprises two independent 4-bit binary counters, each having a clear (CLR)\ and a clock (CLK) input. The device changes state on the negative-going transition of the CLK pulse. N-bit binary counters can be implemented with each package, providing the capability of divide by 256. The SN74LV393A has parallel outputs from each counter stage so that any submultiple of the input count frequency is available for system timing signals.

This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
