描述 Description

The NCID94xx is a galvanically isolated high−speed quad−channel
digital isolator with output enable. This device supports isolated
communications thereby allowing digital signals to communicate
between systems without conducting ground loops or hazardous
voltages.
It utilizes ON Semiconductor patented galvanic off−chip capacitor
isolation technology and optimized IC design to achieve high
insulation and high noise immunity, characterized by high common
mode rejection and power supply rejection specifications. The thick
ceramic substrate yields capacitors with ~25 times the thickness of
thin film on−chip capacitors and coreless transformers. The result is a
combination of the electrical performance benefits that digital
isolators offer with the safety reliability of a >0.5 mm insulator barrier
similar to what has historically been offered by optocouplers.
The device is housed in a 16−pin wide body small outline package.
