NE555D

The NE555 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 NE555 is stable controller capable of producing accurate time delays of frequencies.

Applications

• Precision timing
• Pulse generation Sequential timing
• Time delay generation
