XL239 – Quad Voltage Comparator – Xinluda

About this part

The Xinluda XL239 is a quad differential voltage comparator integrating four independent comparators on a single chip. Functionally part of the industry-standard LM239 comparator class, it is designed to operate from a single power supply over a wide voltage range and offers open-drain outputs that interface with TTL and CMOS logic. The XL239 is supplied in a compact SOP-14 surface-mount package, making it well suited for space-constrained industrial and consumer designs.

Key Features

• Four independent voltage comparators in one package
• Wide single-supply operating range: 2 V to 30 V (absolute maximum 36 V)
• Low input offset voltage: 3 mV (typical)
• Low input bias current: 25 nA
• Low input offset current: 5 nA
• Low supply current: 300 uA per comparator (typical)
• Open-drain output stage
• Output compatible with TTL and CMOS logic levels
• Response time: approximately 1.3 us
• Operating temperature range: -25 C to +85 C
• SOP-14 surface-mount package

Applications

• Limit and threshold (window) comparators
• Zero-crossing and level detection
• Analog-to-digital interface and signal conditioning
• Battery and power-supply monitoring
• Industrial control and sensor circuits
• Oscillators and pulse/timing generation

Why Source XL239 from Pacific Component Xchange

The XL239 from Xinluda has little to no authorized-distributor coverage, which makes it difficult to source through mainstream channels. Pacific Component Xchange specializes in hard-to-find and end-of-life power-management ICs, comparators, and optocouplers. As an independent distributor, we help engineering and procurement teams secure these scarce parts for prototype builds, production runs, and end-of-life replacements.

Every order is backed by our authenticity and quality-assurance process, and we ship worldwide to keep your production lines moving. Because the XL239 is a request-for-quote item, pricing and lead time are provided on request. Submit an RFQ today and our sourcing team will confirm availability, packaging, and delivery for your XL239 requirement.
