DS90LV019TMTC/NOPB

Overview

The DS90LV019TMTC/NOPB is a low-voltage differential signaling (LVDS) interface integrated circuit manufactured by Texas Instruments. It integrates one LVDS driver and one receiver within a single package, designed for high-speed point-to-point interconnects. The device operates on a single 3.3-V or 5-V power supply and supports data rates up to 100 Mb/s. It accepts LVCMOS, LVTTL, or LVDS inputs and provides TTL, LVTTL, or LVDS outputs. Key electrical parameters include a maximum supply voltage of 5.5 V, a minimum of 3 V, and an operating temperature range from -40°C to +85°C. The component features a propagation delay of 7 ns, consumes 48 mA at 3.3 V, and dissipates 790 mW. It is housed in a 14-pin TSSOP surface-mount package.

Feature Summary

• Supports flexible logic interfaces with independent driver enable and receiver output enable controls for enhanced design flexibility.
• Provides balanced output impedance to ensure signal transmission stability and reliability across the link.
• Features glitch-free power-up and power-down characteristics to prevent system instability during state transitions.

Applications

• High-speed point-to-point digital data transmission links
• Industrial control systems requiring robust noise immunity
• Medical equipment with strict signal integrity requirements

Procurement Notes

Verify the specific suffix TMTC against the official datasheet to confirm the TSSOP-14 package variant. Ensure the NOPB designation confirms lead-free and RoHS compliance status as per current regulatory standards. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when a single-channel LVDS transceiver is required for 100 Mb/s applications. It is suitable for designs needing compatibility with both 3.3-V and 5-V logic families. Consider the TSSOP-14 footprint constraints and the industrial temperature range limits during the initial schematic capture phase to ensure proper thermal management.

Part Context

This device belongs to the DS90LV019 series of LVDS interface ICs from Texas Instruments. The series focuses on providing low-power, high-speed differential signaling solutions for embedded systems. The TMTC/NOPB designation specifically identifies the commercial-grade, lead-free version packaged in a thin-shrink small-outline package, distinguishing it from automotive or wider-temperature variants.

Replacement Considerations

Direct pin-compatible replacements within the same family may include other DS90LV019 variants with different packaging options. Verify that any substitute maintains the 100 Mb/s data rate capability and the 3.3-V/5-V dual-supply operation mode to ensure functional equivalence in existing circuits.
