NE555M from HGSEMI, in a SOP-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 reference; common return path. |
| 2 | RTIG | input | Trigger input; timing cycle initiated when voltage falls below 0.333×Vcc; input current 0.5-2 μA. |
| 3 | OUT | output | Totem-pole logic output; maximum source/sink current 200 mA; high-level voltage 13.3V (Vcc=15V) or 3.3V (Vcc=5V). |
| 4 | R | input | Active-low asynchronous reset input; reset voltage 0.4-1V; reset current 0.1-0.4 mA. |
| 5 | CONTRIG | input | Control voltage input for threshold adjustment; nominal voltage 2.6-4V (Vcc=5V) or 9-11V (Vcc=15V). |
| 6 | CONTH | input | Threshold comparator input; output discharge activated at 0.667×Vcc; threshold current 0.1-0.25 μA. |
| 7 | DIS | output | Open-collector discharge transistor; saturation voltage 80-200 mV at 4.5 mA discharge current; leakage current 20-100 nA. |
| 8 | VCC | power_in | Positive power supply; operating voltage range 4.5-16V; quiescent current 3-6 mA (Vcc=5V) or 10-15 mA (Vcc=15V). |
