CXCO4335是一个带输出使能（OE）输入的等效双向I2 C和SMBUS电压电平转换器，工作电压范围为1.2V至3.3V VCCA和2.5V至5.5V VCCB。它允许在1.2V和5V之间进行双向电压转换，而无需使用定向引脚。开关的低导通电阻（rON）保证了连接具有最小的传播延迟。当OE高时，转换器开关打开，并且AN I/O分别连接到BN I/O，允许端口之间的双向数据流。当OE低时，转换器开关关闭，端口之间存在高阻抗。上拉电阻包括在输入和输出线上，在转换器的总线上提供逻辑高电平。上拉电阻的尺寸为10kΩ，通过增加外接电阻，允许使用较低的上拉电阻值至最小1kΩ。所有通道具有相同的电特性，并且在电压或传播延迟方面，从一个输出到另一个输出的偏差最小。由于开关的制造是对称的，所以这比离散平移解有好处。

产品概述 返回TOP
The CXCO4335 is a qual bidirectional I2 C and SMBUS voltage-level translator with an output enable (OE) input, and is operational from 1.2V to 3.3V VCCA and 2.5V to 5.5V VCCB. It allows bidirectional voltage translations between 1.2V and 5V, without use of directional pin. The low ON-state resistance (rON) of the switch ensures the connections to be with minimal propagation delay. When OE is high, the translator switch is ON, and the AN I/O are connected to the BN I/O, respectively, allowing bidirectional data flow between ports. When OE is low, the translator switch is off, and a high-impedance exists between ports. Pull-up resistors are included on input and output lines internally to provide the logic high levels on the translator’s bus. The size of the pull-up resistors are 10kΩ, and is allowed to use lower pull-up resistor value to minimal 1kΩ by adding external resistor. All channels have the same electrical characteristics, and there is minimal deviation from one output to another in voltage or propagation delay. This is a benefit over discrete translation solutions, since the fabrication of the switch is symmetrical.
