Pinout

The LMC555CMMX is a CMOS timer IC with a 8-pin configuration. The pin count and functions are as follows:
1. GND: Ground connection.
2. TRIG: Trigger input; a falling edge on this pin starts the timing interval.
3. OUT: Output; provides the timing signal.
4. RESET: Resets the timer; active low.
5. CTRL: Control voltage; used to override the timing capacitor's voltage.
6. THRS: Threshold input; voltage level that resets the flip-flop.
7. DISCH: Discharge pin; connected to the timing capacitor and used to discharge it when the timer is off.
8. VCC: Power supply voltage input.
The LMC555 is designed for low power applications, offering a wide range of timing and pulse-width modulation capabilities.
