General Description
The ’AC/’ACT169 is fully synchronous 4-stage up/down counter. The ’AC/’ACT169 is a modulo-16 binary counter. It 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.

Features
■ ICC reduced by 50%
■ Synchronous counting and loading
■ Built-In lookahead carry capability
■ Presettable for programmable operation
■ Outputs source/sink 24 mA
■ ’ACT has TTL-compatible inputs
■ Standard Microcircuit Drawing (SMD) 5962-91603
