IP4252-TTL

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 π-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) Nexperia IP4251/52/53/5...
