74F169
4-Stage Synchronous Bidirectional Counter
General Description
The 74F169 is a fully synchronous 4-stage up/down
counter. The 74F169 is a modulo-16 binary counter. Fea-
tures 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.
Features
s Asynchronous counting and loading
s Built-in lookahead carry capability
s Presettable for programmable operation
