This is a precision clock that can time from microseconds to hours, has an adjustable duty cycle, can be used for oscillation or monostable operation, and has a TTL-compatible output that can sink or source up to 200 mA.
The NA555, NE555, SA555 and SE555 are precision timing ICs from Texas Instruments that can operate in astable or monostable modes. They feature adjustable duty cycle, TTL‑compatible outputs, and can sink or source up to 200 mA.
The document provides detailed electrical characteristics, absolute maximum ratings, recommended operating conditions, mechanical dimensions and ordering information for the various package types (D, P, PS, PW, JG, FK).
