ST3DV520E集成电路（IC）的模拟开关-特殊用途规格书PDF中文资料

ST3DV520E属于集成电路（IC）的模拟开关-特殊用途。由意法半导体集团制造生产的ST3DV520E模拟开关 - 特殊用途特殊用途模拟开关通过固态设备路由模拟信号。该系列产品的与众不同之处在于，这些模拟开关针对特定的应用，因此具有通用模拟开关通常所没有的独特功能。

描述 Description

The ST3DV520E is a 4 differential channel LVDS multiplexer/demultiplexer low RON bidirectional switch used to switch between multiple LVDS sources. It is designed for very low crosstalk, low bit-to-bit skew and low I/O capacitance, to maintain high signal integrity.

The differential signal from the LVDS transceiver is multiplexed into one of two selected outputs while the unselected switch goes to Hi-Z status.

The device integrates 2 SPDT (single pole dual throw) switches, for DDC channel.

SEL for LVDS and DDC channel is controlled independently.
