DS36954MX

Overview

The DS36954MX is a low-power, quad EIA-485 differential bus transceiver designed for high-speed, parallel, multipoint I/O bus applications. It operates within a supply voltage range of 4.75 V to 5.25 V and supports an operating free air temperature from 0°C to +70°C. The device features greater than 60 mA source/sink currents and includes thermal shutdown protection with glitch-free driver outputs on power-up and down. It is housed in a compact 20-pin SOIC package.

Feature Summary

• Pinout optimized specifically for SCSI interface implementations
• Compact surface mount packaging providing high integration and minimal PCB footprint
• High drive capability exceeding 60 mA source and sink currents
• Integrated thermal shutdown protection and glitch-free driver outputs during power transitions

Applications

• High-speed parallel multipoint I/O bus systems
• SCSI initiator or target interface implementations
• Multipoint bus transmission networks compliant with EIA-485 standards

Procurement Notes

Verify the specific ordering suffix MX against current TI documentation to confirm tape-and-reel packaging and RoHS compliance status. Confirm active production status and lead times directly with authorized distributors, as availability may vary by region and date.

Selection Notes

Select this component when designing parallel interfaces requiring four independent differential channels within a single package. Ensure the application environment remains within the specified 0°C to +70°C temperature range and utilizes a 5V supply rail compatible with EIA-485 signaling requirements.

Part Context
