74AC169

4-Stage Synchronous Bidirectional Counter

General Description

Features

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.

■ I_CCreduced by 50%

■ Synchronous counting and loading

■ Built-In lookahead carry capability

■ Presettable for programmable operation

■ Outputs source/sink 24 mA
