ULN2065B

The ULN2065B is a high-voltage, high-current Darlington transistor array primarily used for driving inductive loads such as relays, solenoids, and DC motors. It comprises an array of seven NPN Darlington pairs, each capable of driving up to 1.5 A with a maximum voltage of 50 V. The device integrates clamp diodes for handling back EMF generated by inductive loads, ensuring protection and reliability. This makes it particularly suitable for interfacing between logic circuits and higher power loads in applications such as automotive, industrial control, and robotics.
The ULN2065B features a 2.7 kΩ base resistor for each Darlington pair, allowing direct interfacing with TTL or CMOS logic levels. Packed in a 16-pin DIP or SOIC package, it offers compact and efficient circuit integration. Its robust design and ease of use make it a popular choice for designers needing reliable performance in driving inductive loads with minimal external components.

The ULN2065B is a high-voltage, high-current Darlington transistor array commonly used for driving inductive loads. It typically comes in a 16-pin package. The pin configuration is as follows:
1. Pins 1-7 and 10-15: These are the input pins. They receive the input signals that control the corresponding outputs.
2. Pins 9 and 16: These are the ground (GND) pins and are connected to the circuit ground.
3. Pins 8 and 18 (not commonly listed for a 16-pin package): These would typically be connected to the common free-wheeling diode cathodes for clamping inductive loads, but in many configurations, pin 8 is connected to the common free-wheeling diode cathode while pin 18 may not exist for a 16-pin package.
4. Pins 17 (not part of the 16-pin package): If present in other configurations, it would be the common pin for the free-wheeling diodes, in some uses.
The ULN2065B is used to drive high-power loads such as motors, relays, and lamps, offering built-in flyback diodes for inductive load clamping.
