Overview
The SN65LVDM176DGK is a high-speed differential line transceiver produced by Texas Instruments. This device is configured as a transceiver that utilizes low-voltage differential signaling (LVDS) to achieve signaling rates as high as 400 Mbit/s. It is designed for half-duplex operation and is similar to TIA/EIA-644 standard compliant devices, with the output current of the drivers doubled to support double-terminated lines and half-duplex operation.

Applications
The SN65LVDM176DGK is intended for half-duplex or multiplex baseband data transmission over controlled impedance media with approximately 100-Ω characteristic impedance. This includes applications such as printed-circuit board traces, backplanes, or cables. The device is suitable for environments where high-speed data transmission is required, and the transmission media's attenuation characteristics, noise coupling, and other application-specific factors need to be considered.
