DESCRIPTION

The M54/74HC390 is a high speed CMOS DUAL

DECADE COUNTER fabricated in silicon gate

C²MOS technology. It has the same highspeed per-

formance of LSTTL combined with true CMOS low

power consumption.

This dual decade counter contains two independent

ripple carry counters. Each counter is composed of

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

divide-by-two and divide-by-five counters can be

cascaded to form dual decade, dual biquinary, or

various combinations up to a single divide-by-100

counter.

Each 4-bit counter 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 low all four bits of each counter are set to low.

This enables count truncation and allows the im-

plementation of divide-by-N counter configurations.

NC =

No Inter-

nal Con-

All inputs are equipped with protection circuits

against static discharge and transient excess volt-

age.
