ICM7216B Datasheet | Intersil

ICM7216A, ICM7216B, ICM7216D August 1997 8-Digit, Multi-Function, Frequency Counters/Timers Description The ICM7216A and ICM7216B are fully integrated Timer Counters with LED display drivers. They bine a high frequency oscillator, a decade timebase counter, an 8-decade data counter and latches, a 7-segment decoder, digit multiplexers and 8-segment and 8-digit drivers which directly drive large multiplexed LED displays. The counter inputs have a maximum frequency of 10MHz in frequency and unit counter modes and 2MHz in the other modes. Both inputs are digital inputs. In many applications, amplification and level shifting will be required to obtain proper digital signals for these inputs....
