DESCRIPTION
The counters are cascadable. In single stage applications the ”0” output is applied to the Preset Enable input. The cascade feedback input allows cascade divide-by-N operation with no additional gates required. The clock Inhibit input allows disabling of the pulse counting function.APPLICATIONS
for these programmable divide-by-N counters include frequency synthesizers, phaselocked loops and other frequency dividing circuits where low power and/or high noise immunity is required. September 1990 1/6 Plastic DIP16 (0.25)MECHANICAL DATA
