Overview
The SN65LVDS387DGG is a high-speed, 16-channel Low-Voltage Differential Signaling (LVDS) driver produced by Texas Instruments. This component is part of a family of differential line drivers that implement the electrical characteristics of LVDS, designed to reduce power consumption, increase switching speeds, and operate with a 3.3-V supply rail. The device is packaged in a 64-pin Thin Shrink Small-Outline Package (TSSOP) and is characterized for operation over a temperature range of –40°C to 85°C.
