555 datasheet pdf


The 555 is a monolithic timing circuit fabricated using the TI LinCMOS process. The timer is fully
compatible with CMOS, TTL, and MOS logic and operates at frequencies up to 2 MHz. Because of its
high input impedance, this device supports smaller timing capacitors than those supported by the NE555 or LM555. As a result, more accurate time delays and oscillations are possible. Power consumption is low across the full range of power-supply voltage.



1. Very low power consumption :  1-mW typical at VDD = 5 V

2. Capable of operation in astable mode

3. CMOS output capable of swinging rail to rail

4. High output current capability
– Sink: 100-mA typical
– Source: 10-mA typical

5. Output fully compatible with CMOS, TTL, and MOS

6. Low supply current reduces spikes during output transitions
