Product Description
LTV-814 / 824 / 844 Series Optocouplers
The LTV-814/824/844 series are high-performance optocouplers featuring AC input response, high input-output isolation voltage (5,000Vrms), and low collector dark current. They offer excellent current transfer ratio (CTR) and fast response times, making them suitable for various electronic applications requiring signal isolation and transmission. Available in single, dual, and quad-channel configurations, with options for standard, wide lead spacing, and surface mounting packages, including tape and reel for automated assembly.
