Product Description
Product Overview
The LTV-8xx series are AC input, high isolation voltage photocouplers designed for various electronic applications. They offer excellent input-output isolation (5,000Vrms), low collector dark current, and good current transfer ratio (CTR) with fast response times. Available in single, dual, and quad-channel configurations, with options for standard dual-in-line, wide lead spacing, and surface mounting packages, these photocouplers are suitable for a wide range of industrial and consumer electronics.
