The Maxim ICM7217 family of 4 digit presettable
up/down counters contain a 4 digit, 7 segment LED
display driver and a presettable comparison (predeter-
mining) register. The counter and comparison register
can be preset using either thumbwheel switches,
jumpers, or external digital logic.
The ICM7217 (common anode) and ICM7217A (com-
mon cathode) are decade counters with a maximum
count of 9999. The ICM7217B (common anode) and
ICM7217C (common cathode) are modul060 counters
intended for hours/minutes or minute/seconds timing
applications. and have a maximum count of 5959.
These devices also provide multiplexed BCD outputs, a
Carry/Borrow output allowing ICM7217s to be cas-
caded. 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
