DESCRIPTION
The HC690/691/692/693 are high speed CMOS
COUNTER/REGISTER fabricated in silicon gate
C2MOS 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
