High Speed Dual-Channel, Bi-Directional Ceramic Digital Isolator

Favorite

Overview

The NCID9211 is a galvanically isolated full duplex,bi−directional, high−speed dual−channel digital isolator with outputenable. This device supports isolated communications therebyallowing digital signals to communicate between systems withoutconducting ground loops or hazardous voltages.It utilizes ON Semiconductor patented galvanic off−chip capacitorisolation technology and optimized IC design to achieve highinsulation and high noise immunity, characterized by high commonmode rejection and power supply rejection specifications. The thickceramic substrate yields capacitors with ~25 times the thickness ofthin film on−chip capacitors and coreless transformers. The result is acombination of the electrical performance benefits that digitalisolators offer with the safety reliability of a >0.5 mm insulator barriersimilar to what has historically been offered by optocouplers.The device is housed in a 16−pin wide body small outline package.
