ET2104 4路电平转换IC,适用通讯电平转换, 开漏输入/输出. TSSOP10/CSP12
ET2104 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 ET2104 also works in a push-pull
environment. It is intended for use as a voltage translator between I2C-Bus compliant masters and sl***es. Internal 10KΩ pull-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 four ports of the device h***e automatic direction-sense capability. Either port may sense an input signal and transfer it as an output signal to the other port.
