Features

•

The TC74HC697A is high speed CMOS UP/DOWN

It achieve the high speed operation similar to equivalent

It counts on the rising edge of the Counter Clock (CCK) input

The internal counters outputs are latched into the output

The outputs (QA~QD) are selected as either internal counter or

Two enable ( ENP , ENT ) inputs and a carry ( RCO ) output

This facilitates easy implementation of n-bit counters without

All inputs are equipped with protection circuits against static
