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 device is designed for low voltage applications with capability of interfacing to a 5V signal environment. ■ 2.3V–3.6V VCC specifications provided ■ 8.0ns tPD max. (VCC = 3.3V), 10µA ICC max. ■ Power down high impedance inputs and outputs ■ Supports live insertion/withdrawal(1) ■ ±24mA output drive (VCC = 3.0V) ■ Implements proprietary noise/EMI reduction circuitry The LCX373 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining CMOS low power dissipation. ■ Latch-up performance exceeds JEDEC 78 conditions ■ ESD performance – Human body model > 2000V – Machine model > 200V ■ Leadless DQFN package Note: 1. To ensure the high impedance state during power up or down, OE should be tied to VCC through a pull-up resistor: the minimum value of the resistor is determined by the current-sourcing capability of the driver.

When the Latch 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 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. www.fairchildsemi.com 2 74LCX373 — Low Voltage Octal Transparent Latch with 5V Tolerant Inputs and Outputs Connection Diagrams D0 D1 D D2 D G O D3 D G O D4 D G O D5 D G O D6 D G O D7 D G O D G O G O LE OE O0 O1 O2 O3 O4 O5 O6 O7 Please note that this diagram is provided only for the understanding of logic operations and should not be used to estimate propagation delays. ©2006 Fairchild Semiconductor Corporation 74LCX373 Rev. 1.8.1 www.fairchildsemi.com 3 74LCX373 — Low Voltage Octal Transparent Latch with 5V Tolerant Inputs and Outputs Logic Diagram Stresses exceeding the absolute maximum ratings may damage the device.

ANTI-COUNTERFEITING POLICY Fairchild Semiconductor Corporation's Anti-Counterfeiting Policy. Fairchild's Anti-Counterfeiting Policy is also stated on our external website, www.fairchildsemi.com, under Sales Support. Counterfeiting of semiconductor parts is a growing problem in the industry. All manufacturers of semiconductor products are experiencing counterfeiting of their parts. Customers who inadvertently purchase counterfeit parts experience many problems such as loss of brand reputation, substandard performance, failed applications, and increased cost of production and manufacturing delays. Fairchild is taking strong measures to protect ourselves and our customers from the proliferation of counterfeit parts. Fairchild strongly encourages customers to purchase Fairchild parts either directly from Fairchild or from Authorized Fairchild Distributors who are listed by country on our web page cited above. Products customers buy either from Fairchild directly or from Authorized Fairchild Distributors are genuine parts, have full traceability, meet Fairchild's quality standards for handling and storage and provide access to Fairchild's full range of up-to-date technical and product information. Fairchild and our Authorized Distributors will stand behind all warranties and will appropriately address any warranty issues that may arise. Fairchild will not provide any warranty coverage or other assistance for parts bought from Unauthorized Sources. Fairchild is committed to combat this global problem and encourage our customers to do their part in stopping this practice by buying direct or from authorized distributors.
