The Xinluda XL2804 is an octal (eight-channel) high-voltage, high-current NPN Darlington transistor array supplied in a surface-mount SOP-18 package. It belongs to the widely deployed ULN280x peripheral-driver family and is the functional equivalent of the industry-standard ULN2804, making it a practical drop-in option for designs that interface low-level logic with relays, lamps, stepper motors, and other inductive or high-current loads. Within Xinluda’s portfolio, the XL2804 is the SOP-18 surface-mount variant; the pin-compatible DIP-18 through-hole version is offered as the XD2804.
Each of the eight channels pairs a Darlington-connected NPN transistor with an integral free-wheeling clamp diode, allowing the device to switch inductive loads safely without external suppression diodes. The XL2804 is specifically optimized for 6 V to 15 V high-level CMOS or PMOS logic inputs, distinguishing it from the TTL-input ULN2803 member of the same family.
The Xinluda XL2804 sees limited authorized-distributor stock, which can stall production runs and repairs that depend on this specific octal Darlington driver. Pacific Component Xchange specializes in hard-to-find and end-of-life power-management ICs and interface drivers, helping engineers and procurement teams secure the parts they need when mainline channels come up empty. Every XL2804 we supply is sourced for authenticity and traceability, with global shipping to keep your build on schedule. Need a quantity quote, lead time, or cross-reference to a ULN2804 equivalent? Submit an RFQ to Pacific Component Xchange today and our sourcing team will respond quickly with availability and pricing.
The XL2804 is an octal (8-channel) high-voltage, high-current NPN Darlington transistor array from Xinluda, supplied in a SOP-18 surface-mount package. It is functionally equivalent to the industry-standard ULN2804 and is used to drive relays, lamps, motors, and other high-current loads from logic-level signals.
Yes. The XL2804 is Xinluda's functional equivalent of the ULN2804 octal peripheral driver, with eight Darlington channels rated to 500 mA and 50 V, integral clamp diodes, and inputs optimized for 6-15 V CMOS/PMOS logic. It can typically be used as a drop-in alternative in ULN2804 designs.
Both are the same octal Darlington driver design. The XL2804 is the SOP-18 surface-mount version, while the XD2804 is the pin-compatible DIP-18 through-hole version. Choose the package that matches your board layout.
Within the ULN280x family, the difference is the input stage. The XL2804 (ULN2804 type) is optimized for 6-15 V CMOS/PMOS high-level logic inputs, whereas the XL2803 (ULN2803 type) is intended for TTL/5 V CMOS inputs. The output ratings of 500 mA and 50 V across eight channels are the same.
Yes. Each of the eight channels includes an integral free-wheeling clamp diode, so the XL2804 can switch inductive loads such as relays, solenoids, and stepper motors without requiring external flyback diodes.
The XL2804 has limited authorized-distributor availability. Pacific Component Xchange sources hard-to-find and obsolete driver ICs like the XL2804. Submit an RFQ and our team will provide current availability, lead time, and pricing.
