DS90LV019TMTC

Overview

The DS90LV019TMTC is a low-voltage differential signaling (LVDS) interface integrated circuit manufactured by Texas Instruments, formerly National Semiconductor. It integrates one LVDS driver and one receiver in a single package. The device supports data rates up to 100 Mb/s and operates on a single 3.3-V or 5-V power supply. It accepts TTL, LVTTL, or LVCMOS inputs and provides LVDS outputs. Key electrical parameters include a propagation delay of 7 ns, a maximum supply voltage of 5.5 V, and a minimum of 3 V. It functions within an industrial temperature range of -40°C to +85°C and is housed in a 14-pin TSSOP surface-mount package.

Feature Summary

• Supports high-speed point-to-point interconnects with data rates exceeding 100 Mbps using LVDS technology for low electromagnetic interference.
• Features flexible logic interfaces compatible with TTL, LVTTL, and LVCMOS standards, allowing direct connection to various digital sources.
• Operates reliably on a single 3.3-V or 5-V power supply with balanced output impedance and wide common-mode input range.
• Includes glitch-free power-up and power-down protection to ensure system stability during transient voltage events.

Applications

• High-speed serial data transmission in industrial control systems
• Point-to-point interconnects between processors and peripheral devices
• Video signal transmission in display interfaces
• Data acquisition systems requiring noise-immune communication

Procurement Notes

Verify the manufacturer designation carefully, as Texas Instruments acquired National Semiconductor. Ensure the specific suffix matches the required package type and environmental rating. Confirm RoHS compliance status through official documentation before procurement. Cross-reference the full part number with current datasheets to validate active status and pinout compatibility.

Selection Notes

Select this component when a combined driver and receiver solution is needed for LVDS links. It is suitable for designs requiring compatibility with standard logic families like TTL or CMOS. Consider the 14-pin TSSOP package for space-constrained PCB layouts. Verify that the operating voltage aligns with the 3.3-V or 5-V system rails available in the target application.

Part Context

This component belongs to the DS90LV019 series of LVDS interface ICs. It was originally developed by National Semiconductor before the company's acquisition by Texas Instruments. The device is designed to replace older discrete LVDS solutions by integrating both transmission and reception capabilities into a single, compact integrated circuit.

Replacement Considerations

Direct replacements may include other parts from the DS90LV019 family with different packaging options, such as SOIC variants. Verify pin-to-pin compatibility and electrical specifications before substituting. Consult official Texas Instruments documentation for approved alternative part numbers within the same product line.
