8-digit, Multi-function, Frequency Counters/timers

The ICM7216A and ICM7216B are fully integrated Timer Counters with LED Display drivers. They combine 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, amplication and level shifting will be required to obtain proper digital signals for these inputs. The ICM7216A and ICM7216B CAN function as a frequency Counter period Counter frequency ratio (fA/fB) Counter time interval Counter or as a totalizing Counter The Counter uses either a 10MHz or 1MHz quartz crystal timebase. For period and time interval, the 10MHz timebase gives a 0.1s resolution. In period average and time interval average, the resolution CAN be in the nanosecond range. In the frequency mode, the user CAN select accumulation times of 0.01s, 0.1s, 1s and 10s. With a 10s accumulation time, the frequency CAN be displayed to a resolution of 0.1Hz in the least signicant digit. There is 0.2s between measurements in all ranges. By Intersil Corporation
