Overview
The SN65LVDS049PWR is a dual flow-through differential line driver-receiver pair manufactured by Texas Instruments. This device utilizes low-voltage differential signaling (LVDS) to achieve high signaling rates of up to 400 Mbps. The driver and receiver electrical interfaces are compliant with the TIA/EIA-644-A standard, making it suitable for point-to-point baseband data transmission over controlled impedance media such as printed-circuit board traces, backplanes, or cables.
The device operates within an industrial temperature range of –40°C to 85°C and is characterized by its flow-through pinout, which simplifies PCB layout. It features high-impedance disable for all outputs, internal fail-safe biasing of receiver inputs, and high-impedance bus pins on power down.
