IP3253

IP3253/IP3254-TTL Integrated 4-, 6- and 8-channel passive EMI-filter network with high-level ESD protection Rev. 1 — 5 May 2011 Product data sheet 1. Produc t profile 1.1 General description The IP3253/IP3254-TTL family consists of 4-, 6- and 8-channel LC low-pass filter arrays designed to filter unwanted RF signals on the I/O ports of portable communication and computing devices. In addition, the IP3253/IP3254-TTL family incorporates diodes which protect downstream components from ElectroStatic Discharge (ESD) voltages up to ±15 kV. These devices are fabricated using monolithic silicon technology integrating up to 8 inductors and 16 diodes in a 0.4 mm pitch 8-, 12- or 16-pin ultra-thin leadless Quad Flat No-leads (QFN) plastic package. 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 LC filter network „ ESD protection to ±15 kV contact discharge according to IEC 61000-4-2, level 4 „ ESD protection to ±30 kV contact discharge according to MIL-STD-883 (method 3015) Human Body Model (HBM) „ QFN plastic package with 0.4 mm pitch and 0.5 mm height 1.3 Applications „ General-purpose ElectroMagnetic Interference (EMI), 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 http://www.Datashe...
