在整个电源电压范围内提供一致的参数性能
高持续电流:200mA
TMUX8211、TMUX8212 和 TMUX8213 是具有闩锁效应抑制并支持高电压的现代模拟开关。每个器件均具有四个独立可控的 1:1 单极单投 (SPST) 开关通道。此器件可在双电源、单电源或非对称电源供电时正常运行,最大电源电压为 100V。TMUX821x 器件可在整个电源电压范围内提供一致的模拟参数性能。TMUX821x 系列可在源极 (Sx) 和漏极 (Dx) 引脚上支持双向模拟和数字信号。
所有逻辑输入均支持 1.8V、3.3V 和 5V 的逻辑电平,并可在电压高达 48V 时进行连接,从而通过控制信号电压实现系统灵活性。失效防护逻辑电路允许在施加电源引脚上的电压之前,先施加逻辑引脚上的电压,从而保护器件免受潜在的损害。
此器件系列具有闩锁效应抑制功能,可防止器件内寄生结构之间的大电流不良事件。闩锁状态通常会一直持续到电源轨关闭为止,并可能导致器件故障。凭借闩锁效应抑制功能,此系列多路复用器能够在恶劣的环境中使用。

N.C. | 12 | 10 | — | No internal connection. |
VDD | 13 | 9 | P | Positive power supply. This pin is the most positive power-supply potential. For reliable operation, connect a decoupling capacitor ranging from 1 µF to 10 µF between VDD and GND. |
VSS | 4 | 1 | P | Negative power supply. This pin is the most negative power-supply potential. In single-supply applications, this pin can be connected to ground. For reliable operation, connect a decoupling capacitor ranging from 1 µF to 10 µF between VSS and GND. |
Thermal Pad | — | The thermal pad is not connected internally. It is recommended that the pad be tied to GND or VSS for best performance. |
