To learn more about ON Semiconductor, please visit our website at 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 latches appear transparent to the data when Latch Enable (LE) is HIGH. When LE is LOW, the data satisfying the input timing requirements is latched. Data appears on the bus when the Output Enable (OE) is LOW. When OE is HIGH, the bus output is in the high impedance state. The inputs tolerate up to 7V allowing interface of 5V systems to 3V systems. Features ■ 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: Devices also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code. Pb-Free package per JEDED J-STD-020B.

Page 4 2 7 4 L V X 3 7 3 Functional Description The LVX373 contains eight D-type latches with 3-STATE standard outputs. When the Latch Enable (LE) input is HIGH, data on the Dn inputs enters the latches. In this con- dition 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 tran- sition of LE. The 3-STATE standard outputs are controlled by the Output Enable (OE) input. When OE is LOW, the standard outputs are in the 2-state mode. When OE is HIGH, the standard outputs are in the high impedance mode but this does not interfere with entering new data into the latches.
