This data sheet provides detailed information on the features and characteristics of the NA555, NE555, SA555, and SE555 precision timers. These devices are precision timing circuits capable of producing accurate time delays or oscillation.
The Texas Instruments precision timers NE555, NA555, SA555 and SE555 are versatile timing circuits that can operate in astable or monostable modes. They provide TTL‑compatible outputs capable of sinking or sourcing up to 200 mA and support supply voltages from 5 V to 15 V.
The document lists ordering information, package drawings, electrical characteristics, absolute maximum ratings and typical performance curves for each device family, along with mechanical dimensions for the PW package.
