DS90C031TM

Overview

The DS90C031TM is a quad CMOS differential line driver manufactured by National Semiconductor, designed for high-speed serial data transmission. It complies with the IEEE 1596.3 LVDS standard, providing four independent differential drivers in a single package. The device operates within a supply voltage range of 3.0V to 3.6V and supports data rates up to 65Mbps. It features an operating temperature range from -40°C to +85°C and is housed in a 16-pin SOIC surface-mount package.

Feature Summary

• Provides four independent differential channels compliant with IEEE 1596.3 LVDS standards
• Enables high-speed serial data transmission with low power consumption
• Supports operation across extended industrial temperature ranges

Applications

• High-speed serial communication interfaces
• Data acquisition systems requiring differential signaling
• Industrial control networks utilizing LVDS protocols

Procurement Notes

Verify the manufacturer designation as National Semiconductor or Texas Instruments, noting that TI acquired NS. Confirm the specific suffix 'TM' corresponds to the commercial grade temperature range (-40°C to +85°C) and the 16-pin SOIC package. Ensure compatibility with IEEE 1596.3 requirements for your specific circuit design.

Selection Notes

Select this component when a quad LVDS driver is required for board-level interconnects. Compare against the DS90LV031 series if lower power consumption is critical, as the C-series may offer different electrical characteristics. Verify that the 65Mbps data rate meets the system bandwidth requirements and that the 3.3V logic levels match the source interface.

Part Context

This part belongs to the DS90C031 family of LVDS line drivers. It serves as a transmitter counterpart to receivers like the DS90C032. The 'C' prefix typically denotes the commercial temperature grade, distinguishing it from military or extended variants. It is part of the broader portfolio of high-speed interface solutions developed by National Semiconductor.

Replacement Considerations

The DS90C031BTMX is a functionally equivalent alternative from the same manufacturer lineage. Check pinout compatibility and ensure the replacement supports the required 65Mbps data rate and 3.3V supply voltage. Verify that the thermal performance of the substitute package matches the original SOIC-16 form factor.
