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 con­sumption.

The internal circuitis composedof 3 stages includ­ing buffer output, which offers high noise immunity
andstableoutput.Thesedevices incorporateasyn­chronous 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
andhaveenableP andenable Tinputsand a ripple­carry output for easy expansion. The regis­ter/counter select input, R/C, selects the counter
when low or the register when high for the three­stateoutputs, QA, QB, QC, and QD.

If the LOADinput (LOAD)is held ”L” DATAinput(A­D) 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 thecounter clear input (CCLR)
isheld”L”, theinternal counteriscleared(synchron­ously to the counter clock for HC692/HC693, and
asynchronously for HC690/HC691). The internal

counter’s outputs are stored in the output registerat
the positiveedge of the register clock (RCK). If the
register clear input(RCLR) is held ”L” the registeris
cleared (synchronously to register clock for

HC692/HC693 and asynchronously for
HC690/HC691).Allinputsare equipped withprotec­tion circuits against static discharge and transient
excessvoltage.
