ET2102
一般说明

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。

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。

Features

● Bi-Directional Interface between Any Two Levels:1.65V to 5.5V

● No Direction Control Needed

● Internal 10K Pull-Up Resistors

● System GPIO Resources Not Required when OE tied to VCCA

● I2C-Bus Isolation

● A/B Port VOL = 175mV (Typical), VIL = 150mV, IOL = 6mA

● Open-Drain Inputs / Outputs

● Works in Push Pull Environment

● Accommodates Standard-Mode and Fast-Mode I2C-Bus Devices

● Fully Configurable: Inputs and Outputs Track VCC

● Non-Preferential Power-Up; Either VCC Can Power-Up First

● Outputs Switch to 3-State if Either VCC is at GND

● Tolerant Output Enable: 5V

● Packaged in 8-Terminal Leadless Ultrathin QFN (1.2mm x 1.4mm)
