N89026

Overview

The N89026 is a legacy modem integrated circuit manufactured by Altera, now part of Intel. It supports data transmission rates up to 2.4 kbps and complies with V.21, V.22, Bell 103, and Bell 212A standards. The component is housed in a 68-pin Plastic Leadless Chip Carrier (PLCC) package, designed for surface-mount technology applications requiring reliable communication interface capabilities.

Feature Summary

• Supports multiple international modem protocols including V.21, V.22, Bell 103, and Bell 212A
• Integrated modem functionality within a single IC package
• Designed for reliable performance in legacy communication systems

Applications

• Legacy fax modem implementations
• Industrial control system communications
• Historical computer peripheral interfacing

Procurement Notes

Verify manufacturer authenticity as Altera was acquired by Intel. Confirm package integrity for the 68-PLCC form factor. Check date codes against shelf-life guidelines provided in Altera handling documents. Ensure compatibility with existing ISA or serial interfaces before integration into modern designs.

Selection Notes

Select this component only for maintenance of existing hardware utilizing 2.4 kbps modems. Consider that newer designs may require higher-speed alternatives. Verify pinout compatibility with current board layouts. Assess long-term availability constraints due to the component's legacy status within the Intel portfolio.

Part Context

This component belongs to the historical product line of Altera, which specialized in programmable logic devices but also produced supporting interface components like modems prior to its acquisition by Intel. The N89026 represents an era where modem functions were often implemented via discrete or semi-integrated chips rather than software-defined solutions.

Replacement Considerations

Public confirmed substitute part numbers are not available in official documentation. Due to the proprietary nature of legacy modem implementations, direct pin-to-pin replacements from other manufacturers are not explicitly documented. System redesign may be necessary.
