Overview
The IP3253CZ8-4-TTL,13 is an integrated ESD protection and data line filter device manufactured by Nexperia. It features a PI-filter topology with LC components rated at 18nH inductance and 25pF capacitance per channel. The component provides four channels of protection within an 8-pin DFN package.
Feature Summary
- Integrates electrostatic discharge (ESD) protection with signal filtering capabilities
- Utilizes a PI-filter architecture combining inductive and capacitive elements for noise suppression
- Designed for high-speed data line applications requiring compact surface-mount solutions
Applications
- High-speed data interface protection
- Consumer circuit ESD mitigation
- Signal integrity enhancement in portable devices
Procurement Notes
Verify the specific suffix TTL,13 to ensure correct tape-and-reel packaging configuration. Confirm active status as some listings indicate end-of-life or discontinuation. Cross-reference the manufacturer designation between NXP Semiconductors and Nexperia USA Inc. to align with current corporate branding and documentation standards.
Selection Notes
Select this component when simultaneous ESD protection and RF interference filtering are required on multiple data lines. The integrated PI-filter design reduces board space compared to discrete components. Ensure the operating voltage and capacitance values meet the specific impedance requirements of the target data bus.
Part Context
This part belongs to the IP3253/IP3254-TTL series of integrated filters. It is functionally related to variants such as IP3254CZ12-6-TTL,13 which offer different channel counts. The product falls under the broader category of EMI/RFI filters and signal conditioning devices provided by the manufacturer.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with alternative models from the same family, such as IP3254CZ8-4-TTL,13, based on specific pinout and electrical parameter requirements.
