54F 74F169
4-Stage Synchronous Bidirectional Counter
General Description
The ’F169 is a fully synchronous 4-stage up down counter
The ’F169 is a modulo-16 binary counter Features a preset
capability for programmable operation carry lookahead for
easy cascading and a U D input to control the direction of
counting All state changes whether in counting or parallel
loading are initiated by the LOW-to-HIGH transition of the
clock
