PI4ULS5V201 1-Bit Bi-directional Level Shifter with Automatic Sensing Features Description V can be Less than, Greater than or Equal to The PI4ULS5V201 is a 1-bit configurable dual CCA V supply bidirectional auto sensing translator that does not CCB 1.2V to 5.5V on A Port and 1.2V to 5.5V on B Port require a directional control pin. The A and B ports are High-Speed with 20 Mb/s Guaranteed Data Rate designed to track two different power supply rails, V CCA for Push-pull application and V respectively. Both the V and V supply CCB CCA CCB High-Speed with 2 Mb/s Guaranteed Data Rate for rails are configurable from 1.2 V to 5.5 V. This allows Open-drain application voltage logic signals on the V side to be translated CCA No Direction-Control Signal Needed into lower, higher or equal value voltage logic signals on Low Bit-to-Bit Skew the V side, and vice-versa. CCB Non-preferential Power-up Sequencing The translator has integrated 10 k pull-up resistors ESD protection exceeds 8KV HBM per JESD22- on the I/O lines. The integrated pull-up resistors are used A114 to pull-up the I/O lines to either V or V . The CCA CCB Integrated 10 k Pull-up Resistors PI4ULS5V201 is an excellent match for open-drain 2 Package: UDFN1.2x1.6-8L and SOT23-6L applications such as the I C communication bus.
