TL2218-285PWR

Overview

The TL2218-285PWR is an Excalibur current-mode SCSI terminator manufactured by Texas Instruments. It provides nine signal line terminations for high-speed data transmission applications. The device operates within a supply voltage range of 3.5 V to 5.5 V and supports an operating temperature range from 0°C to 125°C. It is housed in a 20-TSSOP package with a width of 4.40 mm. This component is designed to ensure signal integrity in SCSI bus architectures by terminating multiple lines simultaneously.

Feature Summary

• Implements current-mode termination technology for SCSI interfaces
• Integrates nine independent signal line terminations in a single package
• Supports wide operating temperature range for industrial environments

Applications

• SCSI bus system termination
• High-speed data transmission interface protection
• Industrial computer peripheral connections

Procurement Notes

Verify the exact part number suffix PWR against official Texas Instruments documentation to confirm the specific packaging type, which indicates cut tape or reel configuration. Ensure the device meets RoHS compliance requirements if mandated by your project specifications. Cross-reference the 20-TSSOP footprint dimensions with your PCB layout guidelines to guarantee mechanical compatibility during assembly.

Selection Notes

Select this component when designing SCSI interfaces requiring integrated multi-line termination. Consider the 20-TSSOP package size constraints and the 3.5 V to 5.5 V supply voltage range. Evaluate the thermal performance capabilities up to 125°C for your specific environmental conditions. Confirm that the current-mode termination characteristics align with your system's signal integrity requirements.

Part Context

This part belongs to the Excalibur family of SCSI interface components developed by Texas Instruments. These devices were engineered to simplify the design of SCSI controllers and peripherals by integrating necessary termination circuitry. The TL2218 series specifically addresses the need for reliable signal termination in legacy and specialized storage systems.

Replacement Considerations

Consult official Texas Instruments substitution guides for compatible alternatives. Verify pinout compatibility and electrical specifications before replacing the original component with any suggested substitute parts.
