说明

TS5V522C 是高带宽模拟开关，可为 VGA 信号开关提供 2:2 双图形交叉解决方案。该器件支持 2 个 VGA 信号源

的开关，可在膝上型电脑中将信号指向两个目的位置中的一个。 TS5V522C 集成 5 个针对 RGB 信号的极高性能

380 Mhz（典型值）SPDT 开关、2 对适用于 HSYNC 与 VSYNC 线路的电平转换缓冲器以及集成型 ESD 保护。 5

个交叉开关均可通过 5 V 或 3.3 V TTL 控制信号控制。

TS5V522C 能够以更少的失真将 VGA 模拟信号带到目标位置。 DC 通道（SCA、SCL）可能需要 VGA 连接器上

+5 Vopen 的漏级，而且可能还需要在目标端上提供上拉电容器。 TS5V522C 数据端上的有源下冲保护电路可感测

下冲事件并确保在适当关闭状态下进行开关，从而可对低至 -2 V 的下冲事件提供保护。

要在上电或关断过程中确保高阻抗状态，OE 必须通过上拉电阻器的 V
