74LCX00FT

Inverter Gates Overview

The 74LCX00FT is a low-voltage CMOS quad dual-input NAND gate manufactured using sub-micron silicon gate and double-layer metal wiring CMOS technology. It operates within a supply voltage range of 2.0 V to 3.6 V, providing high-speed performance comparable to the 5 V AC/ACT family while maintaining lower power consumption. The device features symmetrical output impedance with minimum drive currents of 24 mA at VCC = 3 V. Inputs are 5 V tolerant, allowing direct interfacing between 5 V systems and 3 V environments. It includes protection circuits against static discharge, offering 2 kV ESD immunity.

Inverter Gates Feature Summary

• Features 5 V tolerant inputs for seamless interface between 5 V and 3 V system environments.
• Provides high-speed operation with maximum propagation delay of 4.3 ns at VCC = 3 V.
• Includes power-down protection on inputs and outputs to prevent excessive current draw.
• Offers robust ESD protection with HBM ratings of 2000 V and CDM ratings of 1000 V.

Inverter Gates Applications

• Low-power and high-speed 3.3 V logic applications
• Interfacing 5 V signal environments with 3 V systems
• PCI bus level applications guaranteed at 24 mA

Inverter Gates Procurement Notes

Verify the specific manufacturer designation, as the 74LCX00 series is produced by multiple vendors including Toshiba, Fairchild, and Nexperia. Confirm that the selected component matches the required package type and voltage specifications. Ensure compatibility with existing PCB footprints and check for any RoHS compliance requirements relevant to your manufacturing standards before finalizing procurement.

Inverter Gates Selection Notes

Select this component when designing circuits that require low-voltage operation combined with 5 V input tolerance. It is suitable for applications needing high-speed NAND logic with balanced propagation delays. Consider the 24 mA drive capability for driving moderate loads. Verify that the operating temperature range meets the environmental conditions of the intended application.

Inverter Gates Part Context

This part belongs to the 74LCX series of low-voltage CMOS logic devices. The series is designed to replace older 5 V logic families in modern low-voltage systems. The 74LCX00 specifically provides quad two-input NAND functionality. It shares pinouts and functions with standard 74 series logic but operates at lower voltages for improved power efficiency.

Inverter Gates Replacement Considerations

Direct substitutes include the 74LCX00MTCX from Fairchild Semiconductor. Other compatible options may be available from manufacturers like Nexperia or Texas Instruments, provided they match the 74LCX logic family specifications and package dimensions.
