Overview
The SN65LVDS9638DGK is a high-speed differential line driver produced by Texas Instruments. This component implements the electrical characteristics of low-voltage differential signaling (LVDS), which reduces power consumption, increases switching speeds, and allows operation with a 3.3-V supply rail. The device is part of a family of differential line drivers that include the SN55LVDS31, SN65LVDS31, and SN65LVDS3487, all of which deliver a minimum differential output voltage magnitude of 247 mV into a 100-Ω load when enabled.
