Product data sheet
1. Product profile
1.1 General description
The IP4253CZ8/CZ12/CZ16; IP4254CZ8/CZ12/CZ16 family consists of 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 IP4253CZ8/CZ12/CZ16; IP4254CZ8/CZ12/CZ16 family incorporates diodes to
provide protection to downstream components from ElectroStatic Discharge (ESD)
voltages as high as ±30 kV.
The IP4253CZ8/CZ12/CZ16; IP4254CZ8/CZ12/CZ16 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
I Pb-free and dark green compliant
I 4-, 6- and 8-channel integrated π-type RC filter network
I IP4253CZ8/CZ12/CZ16: 200 channel series resistance, 30 pF (at 2.5 V DC)
channel capacitance
I IP4254CZ8/CZ12/CZ16: 100 channel series resistance, 30 pF (at 2.5 V DC)
channel capacitance
I ESD protection to ±30 kV contact discharge according to IEC 61000-4-2 standard far
exceeding level 4
I MicroPak (QFN compatible) plastic package with 0.4 mm pitch
1.3 Applications
I General purpose ElectroMagnetic Interference (EMI) and Radio-Frequency
Interference (RFI) filtering and downstream ESD protection for:
N Cellular and Personal Communication System (PCS) mobile handsets
N Cordless telephones
N Wireless data (WAN/LAN) systems
N PDAs
