Overview
The SN65MLVD082DGG is an 8-channel half-duplex Multipoint-Low-Voltage Differential Signaling (M-LVDS) transceiver manufactured by Texas Instruments. This device is designed to operate in compliance with the TIA/EIA-899 (M-LVDS) standard, supporting high-speed data transmission up to 250 Mbps and clock frequencies up to 125 MHz. It is packaged in a 64-pin TSSOP (DGG) package, making it suitable for a variety of high-speed data transmission applications.
