Pinout
8| Pin | Name | Functions | Notes |
|---|---|---|---|
| 1 | GND | GND | Ground |
| 2 | TRIG | GPIO | Start of timing input. TRIG < 1/2 CONT sets output high and discharge open. |
| 3 | OUT | GPIO | High current timer output signal. |
| 4 | RESET | GPIO | Active low reset input forces output and discharge low. |
| 5 | CONT | GPIO | Input. Controls comparator thresholds. Outputs 2/3 VDD and allows bypass capacitor connection. |
| 6 | THRES | GPIO | Input. End of timing input. THRES > CONT sets output low and discharge low. |
| 7 | DISCH | GPIO | Output. Open collector output to discharge timing capacitor. |
| 8 | VDD | POWER | Power-supply voltage. |
