ICM7555, ICM7556

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.

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

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.
