The Xinluda XD339 is a monolithic quad voltage comparator housed in a through-hole DIP-14 package. It belongs to Xinluda’s XL339/XD339/XL2901/XD2901 comparator family, a cost-effective, pin-compatible alternative to the industry-standard LM339 quad differential comparator. Each device integrates four independent comparators designed to operate from a single power supply over a wide voltage range, making the XD339 a versatile building block for level detection, threshold sensing, and signal-conditioning circuits.
The XD339 features outputs compatible with TTL, MOS, and CMOS logic, supporting flexible interfacing across logic families. The wide common-mode input range that includes ground, combined with low input offset and low input bias current, makes it well suited for both single-supply and split-supply applications across consumer, industrial, and automotive electronics.
The XD339 is a hard-to-find part with little to no authorized-distributor availability in Western markets. Pacific Component Xchange specializes in locating obsolete, allocated, and hard-to-source comparators and analog ICs like the Xinluda XD339. As an independent distributor, we provide global sourcing, authenticity and quality verification, and worldwide shipping to keep your production lines and service operations running.
This is a Request-For-Quote (RFQ) item. Contact Pacific Component Xchange with your target quantity, date code, and packaging requirements, and our sourcing team will respond with current availability and pricing. Whether you need a single tube for a redesign or volume quantities for production, we help you secure genuine components with confidence.
The XD339 is a quad voltage comparator from Xinluda, integrating four independent differential comparators in a through-hole DIP-14 package. It is part of Xinluda's XL339/XD339 comparator family and is functionally compatible with the industry-standard LM339.
The XD339 is supplied in a through-hole DIP-14 (PDIP-14) package. In Xinluda's naming convention the XD prefix denotes the through-hole DIP version, while the pin-compatible surface-mount SOP-14 version is offered under the XL339 part number.
Yes. The XD339 shares the standard quad-comparator architecture, 14-pin pinout, and LM339-type output configuration, making it a functional and pin-compatible alternative for most LM339 designs. Always confirm critical parameters against your application requirements.
The XD339 has a maximum supply rating of 36V and supports both single-supply and dual (split) supply operation within that rating. Its common-mode input range includes ground and its differential input range extends to +/-36V.
Each of the four comparators provides an output compatible with TTL, MOS, and CMOS logic, allowing flexible interfacing across logic families with an appropriate external pull-up resistor.
The XD339 is a Request-For-Quote (RFQ) item with limited authorized-distributor availability. Pacific Component Xchange can source it through our global supply network. Submit an RFQ with your quantity and requirements for current availability and pricing.
