General purpose CMOS timer; Exact equivalent in most applications for NE/SE555\nLow supply current: 80 uA (typical)\nExtremely low trigger, threshold, and reset currents: 20 pA (typical)\nHigh-speed operation: 500 kHz guaranteed\nWide operating supply voltage range guaranteed 3 V to 16 V over full automotive temperatures\nNormal reset function; no crowbarring of supply during output transition\nCan be used with higher-impedance timing elements than the NE/SE555 for longer time constants\nTiming from microseconds through hours\nOperates in both astable and monostable modes\nAdjustable duty cycle\nHigh output source/sink driver can drive TTL/CMOS\nTypical temperature stability of 0.005 pct / Cel at 25 Cel\nRail-to-rail outputs\n;

Overview The ICM7555 is a CMOS timer providing significantly improved performance over the standard NE/SE555 timer, while at the same time being a direct replacement for those devices in most applications. Improved parameters include low supply current, wide operating supply voltage range, low THRESHOLD, TRIGGER, and RESET currents, no crowbarring of the supply current during output transitions, higher frequency performance and no requirement to decouple CONTROL_VOLTAGE for stable operation.\nThe ICM7555 is a stable controller capable of producing accurate time delays or frequencies.\nIn the one-shot mode, the pulse width of each circuit is precisely controlled by one external resistor and capacitor. For astable operation as an oscillator, the free-running frequency and the duty cycle are both accurately controlled by two external resistors and one capacitor. Unlike the NE/SE555 device, the CONTROL_VOLTAGE terminal need not be decoupled with a capacitor. The TRIGGER and RESET inputs are active LOW. The output inverter can source or sink currents large enough to drive TTL loads or provide minimal offsets to drive CMOS loads.\n
