TLC556CDR from Texas Instruments, in a SOIC-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 | DISCH | output | Open-collector output for discharging the timing capacitor. |
| 2 | THRES | input | Threshold input; when THRES exceeds CONT, output and discharge pins are set low. |
| 3 | CONT | input | Control voltage input that sets comparator thresholds and provides 2/3 VDD reference when open-circuited. |
| 4 | RESET | input | Active-low reset input that forces output and discharge pins low. |
| 5 | OUT | output | High-current timer output signal. |
| 6 | TRIG | input | Trigger input; when TRIG is below 1/2 CONT, output goes high and discharge pin opens. |
| 7 | GND | power_in | Ground connection. |
| 8 | TRIG | input | Trigger input; when TRIG is below 1/2 CONT, output goes high and discharge pin opens. |
| 9 | OUT | output | High-current timer output signal. |
| 10 | RESET | input | Active-low reset input that forces output and discharge pins low. |
| 11 | CONT | input | Control voltage input that sets comparator thresholds and provides 2/3 VDD reference when open-circuited. |
| 12 | THRES | input | Threshold input; when THRES exceeds CONT, output and discharge pins are set low. |
| 13 | DISCH | output | Open-collector output for discharging the timing capacitor. |
| 14 | VDD | power_in | Power supply voltage. |
