DESCRIPTION

The HC690/691/692/693 are high speed CMOS

COUNTER/REGISTER fabricated in silicon gate

MOS technology.

They have the same high speed performance of

LSTTL combined with true CMOS low power con-

sumption.

The internal circuit is composed of 3 stages includ-

ing buffer output, which offers high noise immunity

and stable output. These devices incorporate a syn-

chronous counter, four-bit D-type register, and

quadruple two-line to one-line multiplexers with

three-state outputs in a single 20-pin package. The

counter can be programmed from the data inputs

and have enable P and enable T inputs and a ripple-

carry output for easy expansion. The regis-

ter/counter select input, R/C, selects the counter

when low or the register when high for the three-

state outputs, QA, QB, QC, and QD.

If the LOAD input (LOAD) is held ”L” DATA input (A-

D) are loaded in to the internal counter at positive

edge of counter clock input (CCK). In the counter

mode, internal counter counts up at the positive of

the counter clock. If the counter clear input (CCLR)

is held ”L”, the internal counter is cleared ( synchron-

ously to the counter clock for HC692/HC693, and

asynchronously for HC690/HC691). The internal
