ICM7555 General purpose CMOS timer - NXP
1. General descriptionThe ICM7555 is a CMOS timer providing significantly improved performance over thestandard NE/SE555 timer , while at the same time being a direct replacement for thosedevices in most applications. Improved parameters include low supply current, wideoperating supply voltage range, low THRESHOLD,TRIGGER, andRESET currents, nocrowbarring of the supply current during output transitions, higher frequency performanceand no requirement to decouple CONTROL_VOLTAGE for stable ICM7555 is a stable controller capable of producing accurate time delays the one-shot mode, the pulse width of each circuit is precisely controlled by oneexternal resistor and capacitor.
n Adjustable duty cycle n High output source/sink driver can drive TTL/CMOS n Typical temperature stability of 0.005 % / °C at 25 °C n Rail-to-rail outputs ICM7555 General purpose CMOS timer ... THRESHOLD voltage TRIGGER voltage RESET[1] OUTPUT Discharge switch
