DESCRIPTION
The M74HC697 is an high speed CMOS UP /
DOWN
COUNTER
REGISTER
(3
STATE)
fabricated with sub-micron silicon gate C2MOS
technology.
The M74HC697 is a 4 BIT BINARY COUNTER
with REGISTER.
The device counts on the positive edge of the
counter clock input (CCK) when selected by the
"Counter Mode". If the input U/D is held "H", the
internal counter counts up, and held "L", counts
down. The internal counter’s outputs are stored in
the output register at the positive edge of register
clock (RCK).
The counter features enable P and enable T and a
ripple-carry output for easy expansion. The
register/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. Both
the counter clock CCR and register clock RCK are
positive-edge triggered. The counter clear CCLR
is active low and is asynchronous.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
