Overview
The SN65LVDM176DR 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 or multiplex baseband data transmission over controlled impedance media, such as printed-circuit board traces, backplanes, or cables. The SN65LVDM176DR operates from a single 3.3-V supply and is characterized for operation from –40°C to 85°C, making it suitable for a wide range of applications requiring high-speed data transmission.
