The ICM7217 is a four digit, presettable up/down counter with an onboard presettable register continuously compared 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 was a attempt to make a Sequential Timer with ICM7217 of Intersil, even though it worked well, it was not developed beyond the prototype stage or first iteration. Only when a product is made in some numbers, the documentation and designs become clear, streamlined and seasoned. Multiplexed Presettable Timer
Multi-Instrument Digital Assistant – PIC16F84A – “It contains four instruments in one unit: logic probe, single channel logic state analyzer, frequency counter and serial code receiver.” The Engineer’s Assistant – Erik Grindheim “This compact instrument is intended to be a digital laboratory tool for hardware and, in some cases, software
