Overview
The SN65LVDT14PWRG4 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 the ability to extend cable lengths. The SN65LVDT14 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, particularly at the SPI slave end.
