MM74HC393 Datasheet (Fairchild) - Dual 4-Bit Binary Counter

MM74HC393, Dual 4-Bit Binary Counter

The MM74HC393 counter circuits contain independent ripple carry counters and utilize advanced silicon-gate CMOS technology.

The MM74HC393 contains two 4-bit ripple carry binary counters, which can be cascaded to create a single divide-by-256 counter.

Each of the two 4-bit counters is incremented on
