Drivers & Fanout Buffers | NB3N401S
概览
NB3N401S 是一款 3.3 V 电源四路多点低压差分信号 (M−LVDS) 线路驱动器和接收器。此器件符合 TIA/EIA−899 标准。此器件在 0.0 V 条件下提供 1 型接收器阈值，在 0.1 V 条件下提供 2 型接收器阈值。NB3N401S 支持四种独立的半双工总线配置。四个部分的每个部分都有引脚 (SEL)，用于选择 1 型和 2 型接收器，这些接收器可在低至 50 mV 的差分输入电压下检测总线状态，其共模电压范围为 −1 V 至 3.4 V。1 型接收器具有接近零的阈值 (±50 mV)，差分输入电压迟滞为 25 mV，可防止输出发生振荡，信号慢慢发生变化或出现输入损耗。2 型接收器包括偏移阈值，用于在开路、空载总线和其他故障条件下提供可检测电压。NB3N401S 采用 48 引脚 7 mm x 7 mm x 0.9 mm QFN 封装。
