Overview
The SN65LVDT14PW is a multi-channel Low-Voltage Differential Signaling (LVDS) transceiver produced by Texas Instruments. This device is designed to provide general-purpose, asymmetric, bidirectional communication with high noise immunity, low electromagnetic interference (EMI), and increased cable length. The SN65LVDT14PW combines one LVDS line driver with four terminated LVDS line receivers in a single package, making it ideal for extending asymmetric, bidirectional interfaces such as SPI over long distances. It is typically located at the SPI slave end.
