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 translation between voltages as Non-preferential power-up sequencing high as 3.6V to as low as 1.1V. The A port tracks the either V may be powered-up first CC V level, and the B port tracks the V level. This CCA CCB Outputs remain in 3-STATE until active V level is CC allows for bi-directional voltage translation over a variety reached of voltage levels: 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V. Outputs switch to 3-STATE if either V is at GND CC The device remains in 3-STATE until both V s reach CC Power-off protection active levels allowing either V to be powered-up first. CC Control inputs (T/R , OE) levels are referenced to n Internal power down control circuits place the device in V voltage CCA 3-STATE if either V is removed. CC Packaged in 16-terminal DQFN (2.5mm x 3.5mm) The Transmit/Receive (T/R) inputs independently deter- and 16-terminal MicroMLP (1.8mm x 2.6mm) mine the direction of data through each of the four bits. ESD protections exceeds: The OE input, when HIGH, disables both the A and B 4kV HBM ESD Ports by placing them in a 3-STATE condition. The (per JESD22-A114 & Mil Std 883e 3015.7) FXL4TD245 is designed so that the control pins (T/R and 8kV HBM I/O to GND ESD OE) are supplied by V .
