ICM7226 - Intersil Corporation

ICM7226 8-Digit Multi-Function Frequency Counter/Timer

The ICM7226 is a fully integrated Universal Counter and LED display driver. It combines a high frequency 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 large LED displays. The counter inputs accept a maximum frequency of 10MHz in freque.
