LMC555CN Pinout Equivalent

1：Overview of the LMC555CN:

The LMC555CN is a timer chip based on CMOS technology. Compared to traditional 555 timers, the LMC555CN uses CMOS processes, significantly reducing power consumption, making it excellent for battery-powered devices with high power requirements. The LMC555CN operates over a wide voltage range of 2V to 18V and typically functions within a temperature range of -40°C to 85°C, ensuring stable performance in harsh environments. Its astable mode can generate pulse signals of different frequencies and duty cycles, suitable for clock signals and modulation signals in electronic devices.
