供应 TXS0104EPWR 双向电压电平转换器

TXS0104EPWR

This 4-bit non-inverting translator uses two separate configurable power-supply rails. The A port is designed to

track VccA-VccA accepts any supply voltage from 1.65 V to 3.6 v. Vcca must be less than or equal to Vcce. The

B port is designed to track VccB.VccB accepts any supply voltage from 2.3 V to 5.5v.This allows for low-voltage 

bidirectional translation between any of the 1.8-V，2.5-V,3.3-V,and 5-V voltage nodes.

To ensure the high-impedance state during power up or power down, oE should be tied to GND through a 

pulldown resistor; the minimum value of the resistor is determined by the current-sourcing capability of the 

driver.

Features
. No Direction-Control Signal Needed

这个4位非反转转换器使用两个独立的可配置电源轨。A端口设计用于跟踪VccA VccA接受1.65 V到3.6 V的任何

电源电压。Vcca必须小于或等于Vcce。B端口设计用于跟踪VccB。VccB接受2.3 V到5.5 V的任何电源电压。这允

许在1.8 V、2.5 V、3.3 V和5 V电压节点之间进行低电压双向转换。
当输出使能（OE）输入低时，所有输出都处于高阻抗状态。

TXS0104E的设计使OE输入电路由VccA供电-
为了保证上电或掉电时的高阻抗状态，oE应通过下拉电阻器连接到GND；电阻器的小值由驱动器的电流源能

力决定。
