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)
