TECHNICAL DATA
CMOS general purpose timer
The ILC555 is CMOS RC timers providing significantly improved
performance over the standard SE/NE555 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 ILC555 is stable controller capable of producing
accurate time delays of frequencies.
