ET2102电平转换可完全替代FXMAR2102
日期：2020-8-25“ET2102电平转换代替FXMAR2102”详细介绍
2路电平转换IC,适用通讯电平转换, 开漏输入/输出.
一般说明
ET2102是一款高性能可配置的双向电压双电源转换器。
在广泛的输入和输出电压电平范围内转换。ET2102也可在推挽式中工作。
环境。它用于I2C总线兼容主设备和从设备之间的电压转换器。提供内部10kΩ上拉电阻。
该设备的设计使得A端口跟踪VCCA级别，B端口跟踪VCCB级别。这允许在1.65V到5.5V的任何两个电平之间进行双向A/B端口电压转换。VCCA可以等于1.65V到5.5V的VCCB。任何一个VCC都可以先通电。如果任何一个VCC被移除，内部断电控制电路将设备置于3状态。
该装置的两个端口具有自动方向感功能。任何一个端口都可以检测到输入信号，并将其作为输出信号传输到另一个端口。

ET2102
General Description
The ET2102 is a high-performance configurable dual-voltage-supply translator for bi-directional voltage
translation over a wide range of input and output voltages levels. The ET2102 also works in a push-pull
environment. It is intended for use as a voltage translator between I2C-Bus compliant masters and slaves. Internal 10KΩpull-up resistors are provided.
The device is designed so the A port tracks the VCCA level and the B port tracks the VCCB level. This allows for bi-directional A/B-port voltage translation between any two levels from 1.65V to 5.5V. VCCA can equal VCCB from1.65V to 5.5V. Either VCC can be powered-up first. Internal power-down control circuits place the device in 3-state if either VCC is removed.
The two ports of the device have automatic direction-sense capability. Either port may sense an input signal and transfer it as an output signal to the other port.
