IP4251/52/53/54 Integrated 4-, 6- and 8-channel passive lter network with ESD protection to IEC 61000-4-2, level 4 Rev. 03 6 May 2009 Product data sheet 1. Product prole 1.1 General description The IP425x family consists of 4-, 6- and 8-channel RC low-pass lter arrays which are designed to provide ltering 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 n Pb-free, Restriction of the use of certain Hazardous Substances (RoHS) and dark green compliant n 4-, 6- and 8-channel integrated -type RC lter network n IP4251CZ8/CZ12/CZ16: 100 channel series resistance, 10 pF (at 2.5 V DC) channel capacitance n IP4252CZ8/CZ12/CZ16: 40 channel series resistance, 12 pF (at 2.5 V DC) channel capacitance n IP4253CZ8/CZ12/CZ16: 200 channel series resistance, 30 pF (at 2.5 V DC) channel capacitance n IP4254CZ8/CZ12/CZ16: 100 channel series resistance, 30 pF (at 2.5 V DC) channel capacitance n ESD protection to 30 kV contact discharge according to IEC 61000-4-2 standard far exceeding level 4 n MicroPak (QFN compatible) plastic package with 0.4 mm pitch 1.3 Applications n General purpose ElectroMagnetic Interference (EMI) and Radio-Frequency Interference (RFI) ltering and downstream ESD protection for: u Cellular and Personal Communication System (PCS) mobile handsets u Cordless telephones u Wireless data (WAN/LAN) systems u PDAsIP4251/52/53/54 NXP Semiconductors Integrated 4-, 6- and 8-channel passive lter network 2.
