Integrated 4-, 6- and 8-channel passive filter network with ESD protection

The devices are 4-, 6- and 8-channel RC low-pass filter arrays which are designed to provide filtering of undesired RF signals on the I/O ports of portable communication or computing devices. In addition, the devices incorporate diodes to provide protection to downstream components from ElectroStatic Discharge (ESD) voltages as high as ±30 kV.

The devices are fabricated using monolithic silicon technology and integrate up to eight resistors and sixteen diodes in a 0.4 mm pitch 8-, 12- or 16-pin ultra-thin leadless Quad Flat No-leads (QFN) plastic package with a height of 0.55 mm only.
