Pinout
The SA555D is a variant of the popular 555 timer IC, which typically comes in an 8-pin Dual Inline Package (DIP) or a Small Outline Integrated Circuit (SOIC) package. Here is a brief description of each pin's function:
1. GND (Pin 1): Ground reference voltage, low level (0V).
2. Trigger (Pin 2): The input that triggers the timer to start, typically when it falls below 1/3 of the supply voltage.
3. Output (Pin 3): The output of the timer, which can be high or low based on the operation mode.
4. Reset (Pin 4): Resets the timer when connected to ground; it’s active low.
5. Control Voltage (Pin 5): Allows the modulation of the threshold and trigger levels, typically connected to a capacitor for noise filtering.
6. Threshold (Pin 6): Compares the voltage with a reference level; when it exceeds 2/3 of the supply voltage, the output is reset.
7. Discharge (Pin 7): Discharges the timing capacitor to ground when the output is low.
8. VCC (Pin 8): The supply voltage for the timer, typically between 4.5V to 15V.
