Overview
The SN65LVDT14PWR 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. It is particularly suited for Serial Peripheral Interface (SPI) over LVDS applications, allowing long interconnects between master and slave devices.
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 over long distances. It operates from a single 3.3-V power supply and is housed in a 20-pin TSSOP package, which simplifies PCB layout due to its flow-through pinout.
