ICM7555, ICM7556 FN2867
Rev 1.00
June 28, 2016 General Purpose Timers
The ICM7555 and ICM7556 are CMOS RC timers providing
significantly improved performance over the standard
SE/NE 555/556 and 355 timers, while at the same time being
direct replacements 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 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 555/556 devices, the Control Voltage terminal need not
be decoupled with a capacitor. The circuits are triggered and …
