UNIVERSAL BI-DIRECTIONALEVEL

The PI4ULS3V204 is a 4-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 1.1V to 3.6V. 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 k? 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 PI4ULS3V204 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 1.1V to 3.6V on A Port and 1.1V to 3.6V on B Port High-Speed with 24 Mb/s Data Rate for push-pull application High-Speed with 2 Mb/s Data Rate for open-drain application No Direction-Control Signal Needed Low Bit-to-Bit Skew Non-preferential Power-up Sequencing ESD protection exceeds 8000V HBM per JESD22-A114 Integrated 10 kO Pull-up Resistors
