Overview
The SN65LVDM176DGKG4 is a high-speed differential line transceiver produced by Texas Instruments. This device is designed for half-duplex or multiplex baseband data transmission over controlled impedance media, such as printed-circuit board traces, backplanes, or cables. It operates using low-voltage differential signaling (LVDS) and is compliant with the TIA/EIA-644 standard, but with doubled output current to support double-terminated lines and half-duplex operation.
The SN65LVDM176DGKG4 is characterized for operation from –40°C to 85°C and features low power consumption, high-speed signaling rates up to 400 Mbit/s, and robust ESD protection exceeding 15 kV on bus pins.
