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 Semiconductor’s 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 LVX573 is functionally identical to the LVX373 but with inputs and outputs on opposite sides of the package. The inputs tolerate up to 7V allowing interface of 5V systems to 3V systems. ■ Input voltage translation from 5V to 3V ■ Ideal for low power/low noise 3.3V applications ■ Guaranteed simultaneous switching noise level and dynamic threshold performance Ordering Code: Order Number 74LVX573M 74LVX573SJ 74LVX573MTC Package Number Package Description M20B 20-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-013, 0.300" Wide M20D Pb-Free 20-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide MTC20 20-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide Devices also available in Tape and Reel.

When the enable (LE) input is HIGH, data on the Dn inputs enters the latches. In this condition the latches are transparent, i.e., a latch output will change state each time its D input changes. When LE is LOW the latches store the information that was present on the D inputs a setup time preceding the HIGH-to-LOW transition of LE. The 3-STATE buffers are controlled by the Output Enable (OE) input. When OE is LOW, the buffers are enabled. When OE is HIGH the buffers are in the high impedance mode but this does not interfere with entering new data into the latches.
