NE555PWR from Texas Instruments, in a TSSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground. |
| 2 | TRIG | input | Start of timing input; TRIG < ½ CONT sets output high and discharge open. |
| 3 | OUT | output | High current timer output signal. |
| 4 | RESET | input | Active low reset input forces output and discharge low. |
| 5 | CONT | bidirectional | Controls comparator thresholds; outputs 2/3 × VCC; allows bypass capacitor connection. |
| 6 | THRES | input | End of timing input; THRES > CONT sets output low and discharge low. |
| 7 | DISCH | output | Open collector output to discharge timing capacitor. |
| 8 | VCC | power_in | Input supply voltage, 4.5 V to 16 V. |
