DESCRIPTION

The M74HC698 is an high speed CMOS UP /

DOWN COUNTER REGISTER (3 STATE)

fabricated with silicon gate C

MOS technology.

The M74HC698 is a BCD DECADE 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

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 synchronous.

All inputs are equipped with protection circuits

against static discharge and transient excess

voltage.
