Overview
The SN65LVDT41PWR is a multi-channel Low-Voltage Differential Signaling (LVDS) transceiver produced by Texas Instruments. This device is part of the SN65LVDTxx family, which integrates both LVDS line drivers and receivers into a single package. The SN65LVDT41 specifically combines four LVDS line drivers with one terminated LVDS line receiver, making it ideal for extending asymmetric, bidirectional interfaces such as SPI over long distances. It operates from a single 3.3-V power supply, with a range of 3 V to 3.6 V, and supports signaling rates of at least 250 Mbps. The device is packaged in a 20-pin TSSOP (Thin Shrink Small Outline Package) with a terminal pitch of 26 mils, designed to simplify PCB layout with its flow-through pinout.
