Product 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
