Philips Semiconductors Linear Products Product specification General purpose CMOS timer ICM7555 DESCRIPTION PIN CONFIGURATION The ICM7555 is a CMOS timer providing significantly improved performance over the standard NE/SE555 timer, while at the same D and N Packages time being a direct replacement for those devices in most 1 8 V applications. Improved parameters include low supply current, wide GND DD operating supply voltage range, low THRESHOLD, TRIGGER, and TRIGGER 2 7 DISCHARGE RESET currents, no crowbarring of the supply current during output OUTPUT 3 6 THRESHOLD transitions, higher frequency performance and no requirement to decouple CONTROL VOLTAGE for stable operation. RESET 4 5 CONTROL VOLTAGE The ICM7555 is a stable controller capable of producing accurate ti
