Is Now Part of To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductors system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore ( ), the underscore ( ) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore ( ). Please check the ON Semiconductor website to verify the updated device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please email any questions regarding the system integration to Fairchild questions onsemi.com.

The device allows Fully configurable, inputs track V level CC translation between voltages as high as 3.6V to as low as Non-preferential power-up sequencing either V may CC 1.1V. The A Port tracks the V level, and the B Port CCA be powered-up first tracks the V level. Both ports are designed to accept CCB No power-up sequencing required supply voltage levels from 1.1V to 3.6V. This allows for bi- Outputs remain in 3-STATE until active V level is directional voltage translation over a variety of voltage lev- CC els: 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V. reached The device remains in 3-STATE until both V s reach Outputs switch to 3-STATE if either V is at GND CC CC active levels allowing either V to be powered-up first.
