XD393 – Voltage Comparator – Xinluda

The Xinluda XD393 is a dual independent differential voltage comparator (LM393-type) in a DIP-8 package, featuring open-collector outputs and a wide single-supply operating range up to 36 V.

The Xinluda XD393 is a dual independent voltage comparator designed for single- or split-supply operation across a wide voltage range. Part of the industry-standard 393 / LM393 family, the XD393 integrates two precision differential comparators with open-collector outputs, making it a versatile, drop-in compatible choice for level detection, zero-crossing detection, oscillators, and general signal-conditioning circuits. It is offered here in the through-hole DIP-8 package.

Key Features

• Dual independent differential voltage comparators (2 channels) in one package
• Wide single-supply operating range up to 36 V, with split-supply operation supported
• Open-collector outputs allow wired-AND connection and flexible pull-up to logic rails
• Low input offset voltage (typ. approximately 2 mV) and low input bias current (typ. approximately 25 nA)
• Output compatible with TTL, MOS, and CMOS logic levels
• Pin-for-pin equivalent to the popular LM393 dual comparator
• DIP-8 (8-pin dual in-line) through-hole package

Applications

• Voltage and threshold level detection
• Zero-crossing detectors
• Relaxation oscillators and square-wave generators
• Window comparators and limit alarms
• Battery and power-rail monitoring
• Sensor signal conditioning and interface logic

Why Source XD393 from Pacific Component Xchange

The Xinluda XD393 can be difficult to obtain through authorized channels in North America and the EU, where Xinluda components have limited distribution coverage. Pacific Component Xchange specializes in sourcing hard-to-find and allocated power-management ICs, comparators, and optocouplers from global supply networks. We help engineers and buyers secure the right orderable part, the correct package, and authentic product when standard distributors come up short.

Every order is backed by our authenticity and quality-assurance process, with inspection and traceability available on request. We ship worldwide and can support both prototype quantities and production volumes. Because the XD393 is offered on a request-for-quote basis, pricing and lead time are confirmed per order. Contact Pacific Component Xchange today to request a quote (RFQ) for the XD393 and let our sourcing team find it for you.
