DESCRIPTION

PIN CONNECTIONS (top view)

The HC696/697 are high speed CMOS up/down

counters fabricated with silicon gate C²MOS

technology. They achieve the high speed operation

similar to equivalent LSTTL while maintaining the

CMOS low power dissipation. The HC696/698 are

BCD DECADE COUNTER, and the HC697/699 are

4-BIT BINARY COUNTER. Both devices have

They count on the positive edge of the counterclock

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 CCK and register clock RCK

are positive-edge triggered. The counter clear

CCLR is active low and is synchronous for

HC698/699, and asynchronous for HC696/697.

NC =

No Internal

Connection

All inputs are equipped with protection circuits

against static discharge and transient excess

voltage.
