4-Stage Synchronous Bidirectional Counter
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 con-
trol 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
Y ICC reduced by 50%
Y Synchronous counting and loading
Y Built-In lookahead carry capability
Y Presettable for programmable operation
Y Outputs source sink 24 mA
Y ’ACT has TTL-compatible inputs
Y Standard Military Drawing (SMD)
’AC169 5962-91603
