总线开关型使用MOSFET作为开关,通过外部上拉电阻进行电压电平转换。 由于它只是一个开关,因此不具有电流驱动能力。然而,缓冲器类型从CMOS结构电路输出并进行电平转换。因此,它具有产品特定的驱动能力,并且输出是数字信号。
总线开关型电压转换IC(电平转换器)
总线开关型产品(TC7SPB9306TU)可以通过打开/关闭和使用上拉电阻来执行电压电平转换. OE引脚是控制输入,用于打开/关闭。
通过图1所示的连接,我们将以当输入信号从左侧(输入A)输入时从右侧(输入B)输出的波形为例来说明操作。
根据输入电压电平,使用产品数据表(表1)中指定的 VOHU(输入电平上升特性)作为阈值,输入/输出传输操作分为两个操作。
0 V至VOHU:内部开关打开,将信号从A传输到B,而不改变其电压。
VOHU 或更高:内部开关关闭。VCCB侧的外部上拉电阻将输入电压上拉至VCCB电平。
表1:数据表中显示的VOHU和VOHD特性(TC7SPB9306TU)
缓冲器型电压转换IC(电平转换器)
总线缓冲器使用CMOS电路进行电平转换。因此,它具有产品特定的驱动能力,并且输出是数字信号(图2)。驱动能力的具体值,请参考数据表工作范围中描述的输出电流。
