TLC556IDR from Texas Instruments, in a SOIC-14. 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 | DISCH | output | Open collector output to discharge timing capacitor. |
| 2 | THRES | input | End of timing input; THRES > CONT sets output low and discharge low. |
| 3 | CONT | input | Controls comparator thresholds; outputs 2/3 VDD and allows bypass capacitor connection. |
| 4 | RESET | input | Active low reset input forces output and discharge low. |
| 5 | OUT | output | High current timer output signal. |
| 6 | TRIG | input | Start of timing input; TRIG < 1/2 CONT sets output high and discharge open. |
| 7 | GND | power_in | Ground. |
| 8 | TRIG | input | Start of timing input; TRIG < 1/2 CONT sets output high and discharge open. |
| 9 | OUT | output | High current timer output signal. |
| 10 | RESET | input | Active low reset input forces output and discharge low. |
| 11 | CONT | input | Controls comparator thresholds; outputs 2/3 VDD and allows bypass capacitor connection. |
| 12 | THRES | input | End of timing input; THRES > CONT sets output low and discharge low. |
| 13 | DISCH | output | Open collector output to discharge timing capacitor. |
| 14 | VDD | power_in | Power-supply voltage; 2V to 15V. |
