The XL2981 from Xinluda is an 8-channel high-voltage, high-current source driver array designed to switch high-power loads directly from logic-level control signals. Functionally equivalent to the classic UDN2981/UDN2982-style source drivers, the XL2981 delivers up to 50V and 500mA per output (subject to package power-dissipation limits), making it well suited for driving relays, solenoids, stepper motors, LEDs, and incandescent or other display loads. The companion XD2981 shares the same architecture.
The XL2981 is a specialty Xinluda source driver with limited authorized-distributor coverage, which can make it difficult to source through mainstream channels. Pacific Component Xchange is an independent distributor focused on hard-to-find and obsolete power-management ICs and driver arrays. We help engineers and buyers secure allocation-constrained and end-of-life parts with authenticity verification, inspection, and global shipping.
Because the XL2981 is offered on a Request-for-Quote basis, pricing and lead time are confirmed per order against current available stock. Submit an RFQ to Pacific Component Xchange with your required quantity and target date, and our sourcing team will respond with availability, pricing, and traceability options.
The XL2981 is an 8-channel high-voltage, high-current source driver array from Xinluda. It switches high-power loads of up to 50V and 500mA per channel directly from logic-level control signals, functioning as a high-side (source) driver.
The XL2981 is offered in an 18-pin plastic DIP and an 18-lead SOP (300mil) package. The companion XD2981 shares the same device architecture.
Its inputs are compatible with 5V TTL and 5V to 15V CMOS or PMOS logic outputs, allowing it to interface directly with common microcontroller and logic systems.
Yes. The XL2981 has transient-protected outputs with integral clamp diodes, which makes it suitable for switching inductive loads such as relays, solenoids, and stepper motor windings.
The XL2981 is a specialty Xinluda part with limited authorized-distributor availability. Pacific Component Xchange offers it on a Request-for-Quote basis; submit your quantity and target date for current pricing, lead time, and availability.
The XL2981 is a functionally similar high-side source driver array in the same family as classic UDN2981/UDN2982-type devices, sharing the 50V/500mA, 8-channel, clamp-diode-protected architecture. Confirm exact pin-for-pin and electrical compatibility against the datasheet for your design.
