ICM7217 Datasheet | Intersil

August 1997 4-Digit LED Display, Programmable Up/Down Counter Description 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. Digit and segment drivers are provided to directly drive displays of up to 0.8 inch character height (mon anode) at a 25% duty cycle. The frequency of the onboard multiplex oscillator may be...
