LM555DRG from HANSCHIP semiconductor, 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/power ground. |
| 2 | Trig | input | Trigger input; triggers output high when voltage drops below approximately 1/3 VCC. |
| 3 | Output | output | Output stage with drive capability up to ±200 mA; output voltage range from VOL (0.02-2.8 V at VCC=15V) to VOH (12.75-13.3 V at VCC=15V). |
| 4 | Reset | input | Reset input; active low with voltage range from GND to 0.5 V for low state and 1.5 V to VCC for high state. |
| 5 | Cont | input | Control voltage input for timing modulation and pulse width adjustment; maximum input voltage equal to VCC. |
| 6 | Thres | input | Threshold input for timing control; maximum input voltage equal to VCC. |
| 7 | Disch | output | Discharge pin; open-collector output that sinks current to discharge the timing capacitor; saturation voltage 140-480 mV (VCC=15V, Idis=15mA). |
| 8 | VCC | power_in | Power supply positive; operating voltage range 4.5 V to 15 V with maximum limit of 18 V. |
