ULN2065B Quad Darlington Switch 80V 1.5A PDIP-16
Designed to interface logic to a wide variety of high current, high voltage loads, these devices each contain four NPN Darlington switches delivering up to 1.5 A with a specified minimum breakdown of 50 V and a sustaining voltage of 35 V measured at 100 mA. Inputs of the ULN2065B are compatible with popular 5V logic families.
Features
- Output current to 1.5A for each Darlington.
- Minimum breakdown 80V.
- Sustaining voltage at least 35V.
- Integral suppression diodes.
- Versions compatible with all popular logic families.
PINOUT
| Pin No. | Symbol | Description |
|---|---|---|
| 1 | K | Clamp diode common cathode (connect to the load supply/positive rail for inductive load suppression). |
| 2 | C | Collector (output) — switched connection to common emitter/ground when channel is ON. |
| 3 | B | Base input (logic control input for the corresponding Darlington channel). |
| 4 | GND | Common emitter / ground connection (tie to PCB ground and recommended heatsink copper area). |
| 5 | GND | Common emitter / ground connection. |
| 6 | B | Base input (logic control input for the corresponding Darlington channel). |
| 7 | C | Collector (output) — switched connection to common emitter/ground when channel is ON. |
| 8 | K | Clamp diode common cathode (same as pin 1, diode connection for inductive load suppression). |
| 9 | C | Collector (output) — switched connection to common emitter/ground when channel is ON. |
| 10 | NC | No connection (not internally used). |
