HD74LV393A Datasheet

Dual 4-bit Binary Counters

Manufacturer: Hitachi Semiconductor (now Renesas)

HD74LV393A Overview

The HD74LV393A contain two 4-bit ripple carry binary counters, which can be cascaded to create a single divide-by-256 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 of each counter are set to a low level.
