DS90LV047ATM/DRPB

Overview

The DS90LV047ATM/DRPB is a quad CMOS differential line driver manufactured by Texas Instruments, designed for low-voltage differential signaling (LVDS) applications. It operates within a supply voltage range of 3V to 3.6V and supports data rates up to 400Mbps. The device accepts CMOS or TTL input signals and converts them into LVDS outputs. It features a propagation delay of 1.7ns and consumes approximately 30mA of operating current with a power dissipation of 866mW. The component is housed in a 16-pin TSSOP package with a width of 4.40mm and functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Provides four independent differential drivers for high-speed serial data transmission
• Accepts standard CMOS or TTL logic levels as inputs
• Outputs compliant with LVDS electrical standards for noise immunity
• Operates on a single 3.3V power supply

Applications

• High-speed digital video interfaces
• Data communication equipment requiring LVDS signaling
• Industrial control systems with long cable runs
• Test and measurement instrumentation

Procurement Notes

Verify the specific suffix 'DRPB' against official Texas Instruments documentation, as standard listings typically use 'NOPB'. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure the ordering part number matches the exact package and tape/reel specifications required for your assembly process.

Selection Notes

Select this component when a quad LVDS driver is needed for 3.3V systems. It is suitable for replacing older National Semiconductor equivalents. Consider the TSSOP-16 package constraints and thermal dissipation requirements. Verify that the 400Mbps speed meets the system bandwidth needs.

Part Context

This part belongs to the DS90LV047A family of LVDS interface devices from Texas Instruments. It serves as a successor to earlier National Semiconductor products in the same category. The device is widely used in applications transitioning from parallel buses to serial LVDS links due to its pin count and performance characteristics.

Replacement Considerations

Direct replacements include the DS90LV047ATM/NOPB. Other compatible options may include the ADN4667 from Analog Devices, though pinouts and electrical parameters should be verified carefully.
