DS90LV019TMTC-TI

Overview

The DS90LV019TMTC is a low-power CMOS LVDS driver and receiver manufactured by Texas Instruments, designed for high-speed point-to-point interconnects. It operates on a single 3.3-V or 5.0-V supply and integrates one differential line driver and one receiver within a 14-pin TSSOP package. The device supports data rates up to 100 Mb/s with a propagation delay of 7 ns. It features independent enable controls for the driver and receiver, allowing flexible logic interface configurations. The input types include LVCMOS, LVTTL, and LVDS, while outputs support TTL, LVTTL, and LVDS levels. Operating temperatures range from -40°C to +85°C.

Feature Summary

• Supports 3.3-V or 5.0-V single-supply operation for broad compatibility.
• Enables low electromagnetic interference (EMI) through LVDS signaling technology.
• Provides glitch-free power-up and power-down functionality to ensure system stability.
• Features balanced output impedance to maintain signal integrity during transmission.

Applications

• High-speed point-to-point digital communication links
• Industrial control systems requiring robust signal transmission
• Data acquisition modules with mixed voltage logic interfaces

Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and avoid counterfeit components. Confirm that the operating temperature range aligns with your environmental design constraints before finalizing procurement orders.

Selection Notes

Select this component when designing circuits that require conversion between standard logic levels and differential LVDS signals. It is suitable for applications needing moderate data rates up to 100 Mb/s with minimal power consumption. Consider the TSSOP-14 package dimensions for PCB layout constraints. Ensure the power supply voltage matches either the 3.3-V or 5.0-V rail as specified in the datasheet recommendations.

Part Context

This device belongs to the DS90LV019 series of LVDS interface integrated circuits. It serves as a bridge between single-ended logic families like TTL/CMOS and differential LVDS lines. The series is characterized by its low power consumption and ability to operate across wide voltage ranges, making it a standard choice for legacy system upgrades and new embedded designs requiring reliable serial data transmission.

Replacement Considerations

Direct pin-compatible alternatives may include other single-driver/receiver LVDS transceivers from Texas Instruments or compatible vendors such as ON Semiconductor MC10EP16. Verify electrical parameters like propagation delay and supply current when substituting to ensure signal timing margins are maintained.
