XD1413 – Darlington Transistor Array – Xinluda

About this part

The Xinluda XD1413 is a 7-channel NPN Darlington transistor array integrated circuit belonging to the industry-standard 1413 / ULN2003 driver family. The XD1413 shares the same die and electrical specification as Xinluda’s XL1413 (the manufacturer datasheet describes the “XL/XD1413” as a single 7-channel NPN Darlington transistor array IC); the XD prefix denotes the through-hole DIP-16 variant, while the XL prefix denotes the surface-mount SOP-16 variant of the same device. Each of the seven Darlington pairs provides high current gain and can sink up to 500mA per channel, making the device well suited for interfacing low-current logic to higher-current loads such as relays, solenoids, stepper motors, incandescent lamps, and LED displays.

Integrated free-wheeling suppression diodes on each output allow the XD1413 to drive inductive loads directly without external clamp diodes, simplifying board layout and improving reliability. The inputs are compatible with standard TTL and CMOS logic levels.
