Description
T ODUC T T E PR E ODUC L R O P S E T OB U BSTIT LE SU M7216 IC POSSIB May 2001 ICM7226A, ICM7226B 8-Digit, Multi-Function, Frequency Counter/Timer De.
The ICM7226 is a fully integrated Universal Counter and LED display driver.
Features
* CMOS Design for Very Low Power
* Output Drivers Directly Drive Both Segments of Large 8-Digit LED Displays Digits and
* Measures Frequencies from DC to 10MHz; Periods from 0.5µs to 10s
* Stable High Frequency Oscillator uses either 1MHz or 10MHz Crystal
* B
Applications
* amplification and level shifting will be required to obtain proper digital signals for these inputs. The ICM7226 can function as a frequency counter, period counter, frequency ratio (fA/fB) counter, time interval counter or as a totalizing counter. The devices require either a 10MHz or 1MHz quartz
