Overview
The PACSZ1284-02QR is an ESD protection and termination network designed for IEEE 1284 parallel port applications. Manufactured by onsemi, this surface-mount device integrates RC filtering and EMI suppression capabilities within a compact package. It serves as a pin-compatible replacement for legacy components like the ST1284-01. The component features a 33 Ohm filter configuration to manage signal integrity while providing electrostatic discharge protection for sensitive interface lines.
Feature Summary
- Integrated ESD protection and termination network for parallel ports
- Pin-compatible with ST1284-01 legacy devices
- Includes 33 Ohm RC filtering for EMI suppression
Applications
- IEEE 1284 parallel port interface protection
- ESD protection for data bus lines
- EMI termination in computer peripheral interfaces
Procurement Notes
Verify current availability status as the part may be obsolete. Confirm pin compatibility with existing designs referencing ST1284-01. Ensure the SMD package dimensions match the target PCB footprint. Review the official datasheet for specific electrical characteristics and handling instructions before integration.
Selection Notes
Select this component for designs requiring integrated ESD protection and signal termination in parallel port circuits. It offers a direct drop-in solution for systems previously using the ST1284-01. Consider the SMD form factor for automated assembly processes. Validate that the 33 Ohm termination value aligns with the system's impedance requirements.
Part Context
This device belongs to onsemi's portfolio of ESD protection diodes and TVS diodes. It is categorized under EMI/RFI filters and termination networks. The product line focuses on protecting high-speed digital interfaces from electrostatic discharge events while maintaining signal quality through integrated filtering elements.
Replacement Considerations
The PACSZ1284-02QR is documented as a pin-compatible substitute for the ST1284-01. Designers migrating from older parallel port protection schemes should verify mechanical fit and electrical parameters against the original design specifications.
