3 Description

The SN74LV393B-EP contains eight flip-flops and

additional gating to implement two individual 4-bit

counters in a single package and is designed for 2

V to 5.5 V VCC operation.

This device fully specified for partial-power-down

applications using Ioff. The Ioff circuitry disables

the outputs, preventing damaging current backflow

through the device when powered down.
