Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1B | input | Channel 1 Darlington base input; accepts control logic signals with 30V absolute maximum input voltage to activate the transistor pair. |
| 2 | 2B | input | Channel 2 Darlington base input; accepts control logic signals with 30V absolute maximum input voltage to activate the transistor pair. |
| 3 | 3B | input | Channel 3 Darlington base input; accepts control logic signals with 30V absolute maximum input voltage to activate the transistor pair. |
| 4 | 4B | input | Channel 4 Darlington base input; accepts control logic signals with 30V absolute maximum input voltage to activate the transistor pair. |
| 5 | 5B | input | Channel 5 Darlington base input; accepts control logic signals with 30V absolute maximum input voltage to activate the transistor pair. |
| 6 | 6B | input | Channel 6 Darlington base input; accepts control logic signals with 30V absolute maximum input voltage to activate the transistor pair. |
| 7 | 7B | input | Channel 7 Darlington base input; accepts control logic signals with 30V absolute maximum input voltage to activate the transistor pair. |
| 8 | E | power_in | Common emitter terminal for all seven Darlington pairs; provides ground return path for all collector currents with -2.5A absolute maximum total emitter-terminal current rating. |
| 9 | COM | power_in | Common cathode for internal free-wheeling diodes; typically connected to load supply voltage for inductive load protection with 50V absolute maximum clamp diode reverse voltage. |
| 10 | 7C | output | Channel 7 Darlington collector output; sinks load current up to 500mA maximum with 50V absolute maximum collector-emitter voltage rating. |
| 11 | 6C | output | Channel 6 Darlington collector output; sinks load current up to 500mA maximum with 50V absolute maximum collector-emitter voltage rating. |
| 12 | 5C | output | Channel 5 Darlington collector output; sinks load current up to 500mA maximum with 50V absolute maximum collector-emitter voltage rating. |
| 13 | 4C | output | Channel 4 Darlington collector output; sinks load current up to 500mA maximum with 50V absolute maximum collector-emitter voltage rating. |
| 14 | 3C | output | Channel 3 Darlington collector output; sinks load current up to 500mA maximum with 50V absolute maximum collector-emitter voltage rating. |
| 15 | 2C | output | Channel 2 Darlington collector output; sinks load current up to 500mA maximum with 50V absolute maximum collector-emitter voltage rating. |
| 16 | 1C | output | Channel 1 Darlington collector output; sinks load current up to 500mA maximum with 50V absolute maximum collector-emitter voltage rating. |
