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.

Power Up/Down high impedance provides glitch-free bus loading These octal buffers and line drivers are designed for low- Outputs source/sink 32mA/+64mA voltage (3.3V) V applications, but with the capability to CC Functionally compatible with the 74 series 244 provide a TTL interface to a 5V environment. The LVT244 and LVTH244 are fabricated with an advanced BiCMOS Latch-up performance exceeds 500mA technology to achieve high speed operation similar to 5V ESD performance: ABT while maintaining low power dissipation.
