74AC169
4-Stage Synchronous Bidirectional Counter
General Description
The AC169 is fully synchronous 4-stage up/down counter.
The AC169 is a modulo-16 binary counter. It features a
preset capability for programmable operation, carry looka-
head for easy cascading and a U/D input to control the
direction of counting. All state changes, whether in count-
ing or parallel loading, are initiated by the LOW-to-HIGH
transition of the Clock.
Features
s ICC reduced by 50%
s Synchronous counting and loading
s Built-In lookahead carry capability
s Presettable for programmable operation
s Outputs source/sink 24 mA
