Intersil CMOS RC Timer 7555 (555) SOIC8

The Intersil CMOS RC Timer in an 8-pin SOIC package provides significantly improved performance over standard SE/NE 555/6 and 355 timers. It serves as a direct replacement for those devices in most applications, offering enhanced parameters for modern circuit design.

Key improvements include low supply current, a wide operating supply voltage range, and a low threshold. Additionally, it eliminates the crowbarring of supply current during output transitions, delivers higher frequency performance, and requires no decoupling of the control voltage for stable operation.

This timer is capable of producing accurate time delays or frequencies. It operates in both astable and monostable modes, providing timing capabilities ranging from microseconds through to hours. The high output source/sink driver can readily drive TTL/CMOS logic.
