The Renesas Electronics ICM7555 series 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.

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, high and low
Pb-free (RoHS Compliant)
