SA555N from HGSEMI, in a DIP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground pin providing system reference potential at 0 volts. |
| 2 | RTIG | input | Trigger input for timing control with threshold voltage VTR = 1.67V at VCC = 5V and trigger current ITR = 0.5-2 µA. |
| 3 | OUT | output | Output pin with low voltage VOL = 0.25-0.35V and high voltage VOH = 2.75-3.3V at VCC = 5V. |
| 4 | R | input | Active-low reset input with threshold voltage VR = 0.4-1.0V and reset current IR = 0.1-0.4 mA. |
| 5 | CONTRIG | input | Trigger control input pin for setting timing threshold levels. |
| 6 | CONTH | input | Threshold control input with threshold voltage VTH = 0.667 × VCC and threshold current ITH = 0.1-0.25 µA. |
| 7 | DIS | output | Open collector discharge output pin with leakage current I7 = 20-100 nA in high state and saturation voltage V7 = 80-200 mV at VCC = 4.5V with 4.5 mA discharge current. |
| 8 | VCC | power_in | Positive power supply input with operating range 4.5-16V and typical static current IQ = 6 mA at VCC = 5V. |
