The PI4ULS5V202 is a 2-bit configurable dual supply bidirectional auto sensing translator that does not require a directional control pin. The A and B ports are designed to track two different power supply rails, VCCA and VCCB respectively. Both the VCCA and VCCB supply rails are configurable from 1.2V to 5.5V. This allows voltage logic signals on the VCCA side to be translated into lower, higher or equal value voltage logic signals on the VCCB side, and vice-versa.
The translator has integrated 10 kΩ pull-up resistors on the I/O lines. The integrated pull-up resistors are used to pull-up the I/O lines to either VCCA or VCCB. The PI4ULS5V202 is an excellent match for open-drain applications such as the I2C communication bus.
VCCA can be Less than, Greater than or Equal to VCCB
1.2V to 5.5V on A Port and 1.2V to 5.5V on B Port
High−Speed with 20 Mb/s Data Rate for push-pull application
High−Speed with 2 Mb/s Data Rate for open-drain application
