Overview
The NB3N401S, produced by onsemi, is a 3.3 V supply Quad Multipoint Low Voltage Differential Signals (M-LVDS) line driver and receiver. This device is compliant with the TIA/EIA-899 standard for multipoint data interchange. It supports four independent half-duplex bus configurations, each with the capability to select between Type-1 and Type-2 receivers. The NB3N401S is designed to operate over a wide common-mode voltage range of -1 V to 3.4 V, making it suitable for applications with significant ground noise.
