Description
描述
The PI4ULS5V202 is a 2-bit configurable dual
这是一个2位的可配置的双pi4uls5v202
supply bidirectional auto sensing translator that does not
供应双向自动传感翻译，不
require a directional control pin. The A and B ports are
需要定向控制销。A和B端口
designed to track two different power supply rails, VCCA
轨道设计的两个不同的电源轨，VCCA
and VCCB respectively. Both the VCCA and VCCB supply
和VCCB分别。无论是VCCA和VCCB供应
rails are configurable from 1.2V to 5.5V. This allows
导轨配置从1.2V到5.5V。这允许
voltage logic signals on the VCCA side to be translated
电压逻辑信号在VCCA侧要翻译
into lower, higher or equal value voltage logic signals on
到低，高或同等价值的电压逻辑信号
the VCCB side, and vice-versa.
VCCB侧，反之亦然。
The translator has integrated 10 kΩ pull-up resistors
译者综合10 KΩ上拉电阻
on the I/O lines. The integrated pull-up resistors are used
在I/O线路上。使用集成的上拉电阻
to pull-up the I/O lines to either VCCA or VCCB. The
向上拉的I / O线要么VCCA或VCCB。这个
PI4ULS5V202 is an excellent match for open-drain
pi4uls5v202是漏极开路的一个很好的匹配
applications such as the I2C communication bus.
应用如I2C通信总线。
