适用于漏极开路和推挽应用的 8 位双向电压电平转换器

Texas Instruments TXS0108EPWR

This 8-bit non-inverting translator uses two separate configurable power-supply rails. The A port tracks the VCCA pin supply voltage. The VCCA pin accepts any supply voltage between 1.2 V and 3.6 V. The B port tracks the VCCB pin supply voltage. The VCCB pin accepts any supply voltage between 1.65 V and 5.5 V. Two input supply pins allows for low Voltage bidirectional translation between any of the 1.2 V, 1.8 V, 2.5 V, 3.3 V, and 5 V voltage nodes.

When the output-enable (OE) input is low, all outputs are placed in the high-impedance (Hi-Z) state.

To ensure the Hi-Z state during power-up or power-down periods, tie OE to GND through a pull-down resistor. The minimum value of the resistor is determined by the current-sourcing capability of the driver.

这个8位非反相转换器使用两个独立的可配置电源轨。A端口跟踪VCCA能针电源电压。VCCA能针接受1.2 V和3.6 V B端口之间的任何电压跟踪VCCB引脚的电源电压。该VCCB引脚接受1.65 V和5.5 V输入电源引脚允许低电压双向翻译任何的1.2 V、1.8 V、2.5 V、3.3 V之间的任何电压,5 V电压节点。
当输出使能(OE)的投入低,所有输出均处于高阻抗状态(高阻抗)。
确保电源或断电期间的高阻抗状态,配合原厂通过下拉电阻到GND。电阻器的最小值取决于驱动程序的当前起动能力。
