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.
•
Exact equivalent in most cases for SE/NE555.
•
Low Supply Current.
•
High speed operation – 500 kHz guaranteed.
•
Wide operation supply voltage range – 2 to 18 volts.
•
Timing from microseconds through hours.
•
Operates in both astable and monostable modes.
•
Adjustable duty cycle.
•
High output source/sink driver can drive TTL/CMOS
