IP4253CZ16-8-TTL,1

Overview

The IP4253CZ16-8-TTL,1 is an integrated EMI filter circuit manufactured by Nexperia. It features an RC (Pi) low-pass configuration with eight channels. Each channel incorporates a resistance of 200 Ohms and a total capacitance of 30 pF. The component is housed in a 16-pin UFDFN package with an exposed pad, designated as DFN-3314-16. This design provides effective suppression for electromagnetic interference in high-speed data lines.

Feature Summary

• Integrates an RC Pi-filter network for efficient EMI/RFI suppression
• Provides eight independent filtering channels for multi-line applications
• Utilizes a compact surface-mount package suitable for space-constrained designs

Applications

• High-speed data line protection
• USB interface filtering
• HDMI signal integrity enhancement
• General-purpose EMI suppression in consumer electronics

Procurement Notes

Verify the current lifecycle status before procurement, as discontinuance notifications have been issued. Confirm that the specific TTL variant matches system requirements. Ensure compatibility with the DFN-3314-16 footprint during PCB layout. Check for any product change notifications affecting electrical characteristics or packaging details prior to finalizing orders.

Selection Notes

Select this component when eight-channel EMI filtering is required for high-speed digital interfaces. The fixed 200 Ohm resistance and 30 pF capacitance values define the cutoff frequency characteristics. Consider the thermal performance of the exposed pad for heat dissipation if operating near temperature limits. Evaluate alternative packages only if mechanical constraints prevent the use of the UFDFN form factor.

Part Context

This part belongs to Nexperia's family of integrated EMI filter circuits designed for suppressing noise on data lines. These components replace discrete R-C networks, reducing board space and assembly complexity. The IP425x series specifically targets applications requiring robust signal integrity in environments prone to electromagnetic interference.
