Overview
The SN65LVDS047DR, produced by Texas Instruments, is a quad differential line driver that implements the electrical characteristics of low-voltage differential signaling (LVDS). This device is designed to operate over a wide temperature range from -40°C to 85°C, making it suitable for industrial applications. The SN65LVDS047DR supports high-speed data transmission with signaling rates exceeding 400 Mbps (200 MHz) and is compatible with the TIA/EIA-644 LVDS standard. It features a flow-through pinout that simplifies PCB layout and reduces design complexity.
