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.

Exact equivalent in most cases for SE/NE 555/556 or TLC555/556
Timing from microseconds through hours
Operates in both astable and monostable modes
