HT7555C HT7556C CMOS process ultra-low power single/dual timer Description The HT7555C and HT7556C 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 HT7555C and HT7556C are stable controllers capable of producing accurate time delays or frequencies.
