Overview
The SN65LVDS116, manufactured by Texas Instruments, is a 16-port Low-Voltage Differential Signaling (LVDS) repeater. This device integrates one differential line receiver with sixteen differential line drivers, designed to meet or exceed the requirements of the ANSI EIA/TIA-644 standard. It is optimized for point-to-point or multidrop baseband data transmission over controlled impedance media, such as printed-circuit board traces, backplanes, or cables. The SN65LVDS116 operates over a temperature range of –40°C to 85°C, making it suitable for a wide range of applications.
