HD74LV393A Datasheet (Renesas) - Dual 4-bit Binary Counters

HD74LV393A, Dual 4-bit Binary Counters

The HD74LV393A contain two 4-bit ripple carry binary counters, which can be cascaded to create a single divide-by256 counter.

The HD74LV393A is incremented on the high to low transition (negative edge) of the clock input, and each has an independent clear input.

When clear is set high all four bits

HD74LV393A Features

* VCC = 2.0 V to 5.5 V operation

* All inputs VIH (Max.) = 5.5 V (@VCC = 0 V to 5.5 V)
