Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1B | input | Channel 1 Darlington base input; accepts TTL/CMOS logic signals (2.7-3 V on-state voltage). |
| 2 | 2B | input | Channel 2 Darlington base input; accepts TTL/CMOS logic signals (2.7-3 V on-state voltage). |
| 3 | 3B | input | Channel 3 Darlington base input; accepts TTL/CMOS logic signals (2.7-3 V on-state voltage). |
| 4 | 4B | input | Channel 4 Darlington base input; accepts TTL/CMOS logic signals (2.7-3 V on-state voltage). |
| 5 | 5B | input | Channel 5 Darlington base input; accepts TTL/CMOS logic signals (2.7-3 V on-state voltage). |
| 6 | 6B | input | Channel 6 Darlington base input; accepts TTL/CMOS logic signals (2.7-3 V on-state voltage). |
| 7 | 7B | input | Channel 7 Darlington base input; accepts TTL/CMOS logic signals (2.7-3 V on-state voltage). |
| 8 | E | power_in | Common emitter terminal for all 7 channels; ground reference shared by all Darlington pairs (typically tied to ground). |
| 9 | COM | power_in | Common cathode node for internal flyback diodes; typically connected to the supply voltage for inductive load suppression. |
