Overview
The IP4254CZ12-6-TTL,1 is an integrated passive filter network with ESD protection, fabricated using monolithic silicon technology. It combines up to eight resistors and sixteen diodes in a 0.55 mm height QFN package with a 0.4 mm pitch. The device provides filtering of undesired RF signals on I/O ports and incorporates diodes for downstream component protection against Electrostatic Discharge (ESD) voltages as high as ±30 kV contact discharge according to IEC 61000-4-2.
Feature Summary
- Integrates a π-type RC low-pass filter network for EMI/RFI suppression
- Provides robust ESD protection exceeding Level 4 per IEC 61000-4-2
- Utilizes ultra-thin leadless QFN plastic packaging for space-constrained designs
Applications
- Cellular phone and PCS mobile handsets
- Wireless data (WAN/LAN) systems
- Portable Media Players (PMP)
Procurement Notes
Verify the current manufacturing status before procurement, as this specific part number may be obsolete or superseded by newer revisions within the IP4254CZ series. Confirm that the required channel configuration matches the available variants in the family. Ensure compatibility with RoHS and Dark Green compliance requirements if environmental regulations apply to the final assembly process.
Selection Notes
Select this component when simultaneous EMI filtering and ESD protection are required on high-density I/O lines. The integrated design reduces board space compared to discrete solutions. Consider the specific channel count needs, as the family includes 4-, 6-, and 8-channel variants. Verify that the low-pass filter characteristics meet the signal integrity requirements of the target application interface.
Part Context
This device belongs to Nexperia's portfolio of integrated EMI/RFI filters designed for portable communication and computing devices. It addresses the industry trend toward miniaturization by combining passive filtering and protection functions into a single ultra-thin package. The product line supports various channel configurations to accommodate different pin counts and interface densities in mobile electronics.
Replacement Considerations
Check for updated suffixes or revised datasheets within the IP4254CZ series, as the base part number may have been discontinued. Evaluate equivalent integrated filter networks from other manufacturers if supply continuity is a concern, ensuring matching package dimensions and electrical specifications.
