Overview
The SN65LVDS390PWR, produced by Texas Instruments, is a high-speed differential line receiver that implements the electrical characteristics of low-voltage differential signaling (LVDS). This device is part of a family that includes 4-, 8-, or 16-channel receivers, designed to meet or exceed the requirements of the ANSI TIA/EIA-644 standard. The LVDS signaling technique reduces power consumption, increases switching speeds, and allows operation with a 3-V supply rail, making it suitable for various high-speed data transmission applications.

Applications
The SN65LVDS390PWR is intended for point-to-point baseband data transmission over controlled impedance media of approximately 100 Ω, such as printed-circuit board traces, backplanes, or cables. It is particularly useful in applications requiring high-speed data transfers, such as in synchronous parallel data transfers when used with its companion drivers (SN65LVDS389 or SN65LVDS387). These devices enable over 200 million data transfers per second in single-edge clocked systems with minimal power consumption.
