Pinout
1. Ground (GND): Pin 1 - Connects to the negative supply voltage or ground.
2. Trigger: Pin 2 - A low voltage trigger on this pin initiates the timing interval, causing the output to go high.
3. Output: Pin 3 - The output pin delivers the timer's response, providing either a high or low voltage level depending on the configuration.
4. Reset: Pin 4 - Active-low reset input. Bringing this pin low resets the timer; it's often connected to VCC if not used.
5. Control Voltage: Pin 5 - Allows external voltage control of the threshold and trigger levels; often connected to a capacitor if not used.
6. Threshold: Pin 6 - Monitors the voltage level compared to 2/3 of the supply voltage to reset the output when exceeded.
7. Discharge: Pin 7 - Discharges a capacitor between intervals in astable mode.
8. VCC: Pin 8 - Connects to the positive supply voltage.
The SA555DR is typically used in applications like pulse generation, timing, and waveform generation.
