IP4251/52/53/54-TTL Integrated 4-, 6- and 8-channel passive filter network with ESD protection Rev. 2 5 May 2011 Product data sheet 1. Product profile 1.1 General description 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. 1.2 Features and benefits Pb-free, Restriction of Hazardous Substances (RoHS) compliant and free of halogen and antimony (Dark Green compliant) 4-, 6- and 8-channel integrated -type RC filter network ESD protection to 30 kV contact discharge according to IEC 61000-4-2 far exceeding level 4 QFN plastic package with 0.4 mm pitch and 0.55 mm height 1.3 Applications General-purpose ElectroMagnetic Interference (EMI) and Radio-Frequency Interference (RFI) filtering and downstream ESD protection for: Cellular phone and Personal Communication System (PCS) mobile handsets Cordless telephones Wireless data (WAN/LAN) systems Mobile Internet Devices (MID) Portable Media Players (PMP)IP4251/52/53/54-TTL Nexperia Integrated 4-, 6- and 8-channel passive filter network 1.4 Quick reference data Table 1.
