Details
The ILC555N is a CMOS low power single timer IC that is pin-to-pin compatible with the industry-standard 555 timer. It operates over a voltage range of 2V to 18V and has lower power consumption compared to the traditional 555 timer. The ILC555N features a wide temperature range of -40°C to 125°C, making it suitable for a variety of applications.This timer IC has two operating modes: monostable and astable. In the monostable mode, the output pulse duration is determined by an external resistor and capacitor, whereas in the astable mode, the IC operates as a free-running oscillator. The ILC555N also includes a reset pin that can be used to reset the timing cycle.The ILC555N is widely used in applications such as timers, pulse generators, LED flashers, and tone generators. Its low power consumption and wide voltage range make it suitable for battery-operated devices and portable electronics.
