Overview
The SN65LVDT41PW is a multi-channel Low-Voltage Differential Signaling (LVDS) transceiver produced by Texas Instruments. This device integrates four LVDS line drivers and one terminated LVDS line receiver into a single 20-pin Thin Shrink Small-Outline Package (TSSOP). It operates from a single 3.3-V power supply, which can range from 3 V to 3.6 V, making it versatile for various applications. The SN65LVDT41PW is designed to support signaling rates of at least 250 Mbps and is particularly useful for extending asymmetric, bidirectional interfaces such as Serial Peripheral Interface (SPI) over long distances.
