ICM7217 Overview
The ICM7217 is a four digit, presettable up/down counter with an onboard presettable register continuously pared to the counter. The ICM7217 is intended for use in hard-wired applications where thumbwheel switches are used for loading data, and simple SPDT switches are used for chip control. This circuit provides multiplexed 7 segment LED display outputs, with mon anode or mon cathode configurations available.
