Product profile 1.
1 General description The IP425x family consists of 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 IP425x family incorporates diodes to provide protection to downstream components from ElectroStatic Discharge (ESD) voltages as high as ±30 kV.
The IP425x family is fabricated using monolithic silicon technology and integrates up to 8 resistors and 16 diodes in a 0.
4 mm pitch 8-, 12- or 16-pin MicroPak (compatible with QFN) lead-free plastic package with a height of 0.
5 mm only.
