IP4251

IP4251/52/53/54 Rev. 03 — 6 May 2009 www.DataSheet4U.com Integrated 4-, 6- and 8-channel passive filter network with ESD protection to IEC 61000-4-2, level 4 Product data sheet 1. 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. 1.2 Features I Pb-free, Restriction of the use of certain Hazardous Substances (RoHS) and dark green compliant I 4-, 6- and 8-channel integrated π-type RC filter network I IP4251CZ8/CZ12/CZ16: 100 Ω channel series resistance, 10 pF (at 2.5 V DC) channel capacitance I IP4252CZ8/CZ12/CZ16: 40 Ω channel series resistance, 12 pF (at 2.5 V DC) channel capacitance I IP4253CZ8/CZ12/CZ16: 200 Ω channel series resistance, 30 pF (at 2.5 V DC) channel capacitance I IP4254CZ8/CZ12/CZ16: 100 Ω channel series resistance, 30 pF (at 2.5 V DC) channel capacitance I ESD protection to ±30 kV contact discharge according to IEC 61000-4-2 standard far exceeding level 4 I MicroPak (QFN comp...
