ICM7217IPI+

The ICM7217IPI+ is a 4 digit (LED) presettable up/down counter in 28 pin DIP package. It is a 4 digit presettable up/down counter that contains a 4 digit, 7-segment LED display driver and a presettable comparison register. The counter and comparison register can be preset using either thumb wheel switches, jumpers or external digital logic. This is a decade counter with a maximum count of 9999. This device also provides multiplexed BCD outputs, a carry borrow output allowing ICM217's to be cascaded, a zero output which indicates when the count is equal to zero and an equal output which indicates when the count is equal to the value contained in the comparison register. It also has a reset input and a display latch with store input. Typical applications include predetermining batch counter, tachometer, over/under speed detector, count down/elapsed timer, unit counter and frequency counter.
