Overview
The IP4252CZ16-8-TTL,1 is an 8-channel RC low-pass filter array designed for EMI/RFI suppression. It integrates resistors and capacitors in a UDFN-16 package with dimensions of 1.4x3.3 mm. Key electrical parameters include a characteristic impedance of 50 Ohms, resistance of 40 Ohms per channel, and total capacitance of 12 pF. The device offers insertion loss of 14 dB at 1 GHz and operates within a temperature range of -40°C to +85°C.
Feature Summary
- Integrates eight independent RC low-pass filter channels for multi-line signal protection.
- Provides effective filtering of undesired RF signals on I/O ports.
- Combines ESD protection capabilities with signal integrity enhancement.
Applications
- Filtering RF interference on high-speed digital interfaces
- Signal conditioning for portable electronic devices
- EMI suppression in consumer electronics
Procurement Notes
Verify the specific suffix 'TTL' against the official Nexperia datasheet to confirm pinout and electrical characteristics match design requirements. Confirm availability status as some distributors indicate limited supply or discontinuation notices for related variants. Ensure the UDFN-16 exposed pad footprint aligns with PCB layout guidelines.
Selection Notes
Select this component when designing circuits requiring simultaneous EMI filtering and ESD protection for multiple data lines. The 50 Ohm impedance matches standard transmission line requirements. Consider the compact UDFN-16 package for space-constrained layouts. Verify thermal performance and soldering compatibility for the exposed pad design.
Part Context
This part belongs to Nexperia's IP42xx series of integrated EMI filters. These devices combine passive filtering components with semiconductor protection structures. The series targets applications needing compact solutions for signal integrity and electrostatic discharge mitigation in modern electronic systems.
Replacement Considerations
Check Nexperia documentation for direct pin-compatible alternatives within the IP42xx family. Verify if other channel counts (e.g., 4 or 6 channel versions) meet system requirements. Confirm that any substitute maintains the same 50 Ohm impedance and package dimensions.
