The Intersil ICM7226 is an 8-decade counter and 7-segment driver monolithic integrated circuit.
The ICM7226 combines an oscillator, a decade timebase counter, an 8-decade data counter and latches, a 7-segment decoder, digit multiplexer and segment and digit drivers which can directly drive LED displays.
It can function as a frequency counter, period counter, frequency ratio counter, time interval counter, or as a totalizing counter.
