Overview
The SN65LVDS94 is a Low-Voltage Differential Signaling (LVDS) serdes (serializer/deserializer) receiver produced by Texas Instruments. This integrated circuit is designed to receive synchronous data from compatible transmitters, such as the SN65LVDS93 and SN65LVDS95, over five balanced-pair conductors and expand it to 28 bits of single-ended LVTTL (Low-Voltage Transistor-Transistor Logic) synchronous data at a lower transfer rate. The device operates from a single 3.3-V supply and is characterized for operation over ambient air temperatures of -40°C to 85°C, making it suitable for industrial applications.
