The ICM7555CD/01,118 is a CMOS timer IC manufactured by NXP Semiconductors, designed as an improved replacement for the standard NE/SE555 timer. It offers enhanced performance with low supply current and a wide operating supply voltage range from 3V to 16V.
This timer IC is capable of producing accurate time delays or frequencies, operating in both astable and monostable modes. It supports high-speed operation up to 500 kHz and features rail-to-rail outputs capable of driving TTL/CMOS loads. The device has extremely low trigger, threshold, and reset currents, making it suitable for applications requiring precise timing from microseconds through hours.
Packaged in an 8-SOIC surface-mount configuration, the ICM7555CD/01,118 is designed for ease of integration into electronic circuits. Its typical supply current is 80 µA, and it operates within a temperature range of 0°C to 70°C. The device also boasts typical temperature stability of 0.005% / °C.
Key applications include precision timing, pulse generation, sequential timing, time delay generation, and pulse width modulation. Its design allows for use with higher-impedance timing elements compared to the NE/SE555, enabling longer time constants.
The operating supply voltage range is 3 V to 16 V.
The device supports high-speed operation up to 500 kHz.
The typical supply current is 80 µA.
The operating temperature range is 0°C to 70°C.
It is supplied in an 8-SOIC package.
