ICM7555 SMD General Purpose CMOS Timer SO-8

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. Features Exact equivalent in most applications for NE/SE555 Low supply current: 80μA (typ) Extremely low trigger, threshold, and reset currents: 20pA (typ) High-speed operation: 500kHz guaranteed Wide operating supply voltage range guaranteed 3 to 16V over full automotive temperatures Normal reset function; no crowbarring of supply during output transition Can be used with higher-impedance timing elements than the bipolar 555 for longer time constants Timing from microseconds through hours Operates in both astable and monostable modes Adjustable duty cycle High output source/sink driver can drive TTL/CMOS Typical temperature stability of 0.005%/o C at 25°C Rail-to-rail outputs Specifications Product Attribute Attribute Value Manufacturer: NXP Product Category: Timers & Support Products Type: Standard Number of Internal Timers: 1 Timer Supply Voltage – Max: 16 V Supply Voltage – Min: 3 V Minimum Operating Temperature: 0 C Maximum Operating Temperature: + 70 C Mounting Style: SMD/SMT Package/Case: SOIC-8 Pd – Power Dissipation: 780 mW Applications Precision timing Pulse generation Sequential timing Time delay generation Pulse width modulation Pulse position modulation Missing pulse detector ICM7555 Datasheet
