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. • Exact Equivalent in Most Cases for SE/NE555/556 or TLC555/556 Specifically, the ICM7555 and ICM7556 are stable controllers capable of producing accurate time delays or frequencies. The ICM7556 is a dual ICM7555, with the two timers operating independently of each other, sharing only V+ and GND. In 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 regular bipolar SE/NE 555/6 devices, the CONTROL VOLTAGE terminal need not be decoupled with a capacitor. The circuits are triggered and reset on falling (negative) waveforms, and the output inverter can source or sink currents large enough to drive TTL loads, or provide minimal offsets to drive CMOS loads. • Low Supply Current - ICM7555 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 60μA - ICM7556 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 120μA • Extremely Low Input Currents . . . . . . . . . . . . . . . . . 20pA • High Speed Operation . . . . . . . . . . . . . . . . . . . . . . . 1MHz • Guaranteed Supply Voltage Range . . . . . . . . . 2V to 18V • Temperature Stability . . . . . . . . . . . . 0.005%/°C at +25°C • Normal Reset Function - No Crowbarring of Supply During Output Transition • Can be Used with Higher Impedance Timing Elements than Regular 555/6 for Longer RC 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 • Outputs have Very Low Offsets, HI and LO • Pb-Free Plus Anneal Available (RoHS Compliant) Applications • Precision Timing • Pulse Generation • Sequential Timing • Time Delay Generation • Pulse Width Modulation • Pulse Position Modulation • Missing Pulse Detector Pinouts ICM7555 (8 LD PDIP, SOIC) TOP VIEW ICM7556 (14 LD PDIP, CERDIP) TOP VIEW DISCHARGE 1 GND 1 8 VDD TRIGGER 2 7 DISCHARGE OUTPUT 3 6 THRESHOLD 5 CONTROL VOLTAGE RESET 4 THRESH- 2 OLD CONTROL 3 VOLTAGE RESET 4 OUTPUT 5 TRIGGER 6 GND 7 1 14 VDD 13 DISCHARGE 12 THRESHOLD 11 CONTROL VOLTAGE 10 RESET 9 OUTPUT 8 TRIGGER CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures. 1-888-INTERSIL or 1-888-468-3774 | Intersil (and design) is a registered trademark of Intersil Americas Inc.

This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. NOTES: 1. Due to the SCR structure inherent in the CMOS process used to fabricate these devices, connecting any terminal to a voltage greater than V+ +0.3V or less than V- -0.3V may cause destructive latchup. For this reason it is recommended that no inputs from external sources not operating from the same power supply be applied to the device before its power supply is established. In multiple supply systems, the supply of the ICM7555 and ICM7556 must be turned on first. 2. θJA is measured with the component mounted on a low effective thermal conductivity test board in free air. See Tech Brief 379 for details.
