ICM7217AIPI IC, CONTROL UP DOWN OSC 2MHZ 28-DIP

The ICM7217AIPI+ is a 4-digit (LED) presettable Up/Down Counter contain a 4 digit, 7 segment LED display driver and a presettable comparison (predetermining) register. The counter and comparison register can be preset using either thumbwheel switches, jumpers or external digital logic. The ICM7217A (common cathode) are decade counters with a maximum count of 9999. These devices also provide multiplexed BCD outputs, a carry/borrow output allowing ICM7217s 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. The ICM7217 also has a reset input and a display latch with store input.
