NE556N from XBLW, in a DIP-14. 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 | 1DISCH | passive | Timer 1 discharge pin (open-collector transistor output to ground); leakage 20 nA typ with output high, saturation voltage 180 mV typ at Vcc=15V, Idis=15mA. |
| 2 | 1THRES | input | Timer 1 threshold comparator input; threshold voltage 10 V typ at Vcc=15V and 3.33 V typ at Vcc=5V, maximum input voltage Vcc. |
| 3 | 1CONT | input | Timer 1 control voltage input; control voltage level 10 V typ at Vcc=15V and 3.33 V typ at Vcc=5V. |
| 4 | 1RESET | input | Timer 1 active-low reset (inhibit) input to the flip-flop; maximum input voltage Vcc. |
| 5 | 1OUT | output | Timer 1 output that can source or sink up to 200 mA. |
| 6 | 1TRIG | input | Timer 1 trigger comparator input; trigger voltage 5 V typ at Vcc=15V and 1.67 V typ at Vcc=5V, maximum input voltage Vcc. |
| 7 | GND | power_in | Ground, common to both timers. |
| 8 | 2TIG | input | Timer 2 trigger comparator input; trigger voltage 5 V typ at Vcc=15V and 1.67 V typ at Vcc=5V, maximum input voltage Vcc. |
| 9 | 2OUT | output | Timer 2 output that can source or sink up to 200 mA. |
| 10 | 2RESET | input | Timer 2 active-low reset (inhibit) input to the flip-flop; maximum input voltage Vcc. |
| 11 | 2CONT | input | Timer 2 control voltage input; control voltage level 10 V typ at Vcc=15V and 3.33 V typ at Vcc=5V. |
| 12 | 2THRES | input | Timer 2 threshold comparator input; threshold voltage 10 V typ at Vcc=15V and 3.33 V typ at Vcc=5V, maximum input voltage Vcc. |
| 13 | 2DISCH | passive | Timer 2 discharge pin (open-collector transistor output to ground); leakage 20 nA typ with output high, saturation voltage 180 mV typ at Vcc=15V, Idis=15mA. |
| 14 | VCC | power_in | Positive supply, recommended 4.5 to 18 V with absolute maximum 18 V. |
