Where transient overvoltage protection in ESD
sensitive equipment is required, such as:
Computers
Printers
Communication systems
Cellular phone handsets and accessories
Video equipment
Description
Features
Integrated common mode filter
Differential pair ESD protection
16 V V
BUS
ESD and EOS protection
ID pin ESD protection
Low profile micro QFN-8L package
High bandwidth: > 6 GHz
Optimized for high speed USB 2.0
High common mode attenuation at 900 MHz
and 1.8 GHz
Support for audio over USB 2.0 thanks to
bidirectional ESD protection
