MM54HC390, MM74HC390 / MM54HC393, MM74HC393

Dual 4-Bit Decade Counter / Dual 4-Bit Binary Counter

These counter circuits contain independent ripple carry counters and utilize advanced silicon-

gate CMOS technology. The MM54HC390/MM74HC390 incorporate dual decade counters, each

composed of a divide-by-two and a divide-by-ﬁve counter. The divide-by-two and divide-by-ﬁve

counters can be cascaded to form dual decade, dual bi-quinary, or various combinations up to a

single divide-by-100 counter. The MM54HC393/MM74HC393 contain 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 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. This enables count truncation and allows the implementation of divide-

by-N counter conﬁgurations.
