General Description
The ET2101 is a high-performance configurable voltage-supply translator for bi-directional voltage translation over a wide range of input and output voltages levels. The ET2101 also works in a push-pull environment. It is intended for use as a voltage translator between I2C bus compliant masters and slaves. Internal 10KΩ pull-up resistors are provided.
Features
- Bi-Directional interface between any two levels from 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 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
- Supports I2C clock stretching & multi-master
- 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 up to 5V
