74VHCT04AMX

Inverter Gates Overview

The Fairchild Semiconductor 74VHCT04AMX is a hex inverter integrated circuit fabricated using advanced silicon gate CMOS technology. It operates within a supply voltage range of 4.5V to 5.5V and features six independent inverters, each with one input. The device provides high-speed performance with a typical propagation delay of 4.7ns at 25°C and maintains low power dissipation with a maximum static current of 2µA. It offers symmetrical output impedance with minimum drive currents of 8mA for both high and low states. The component is housed in a 14-pin SOIC package.

Inverter Gates Feature Summary

• Achieves high-speed operation comparable to Bipolar Schottky TTL while maintaining CMOS low power characteristics
• Provides high noise immunity through buffer output stages ensuring stable signal integrity
• Includes power-down protection on all inputs and outputs to prevent damage during voltage mismatches
• Ensures balanced propagation delays with symmetrical output impedance for consistent timing

Inverter Gates Applications

• General-purpose logic inversion in digital circuits
• Level shifting between 3.3V and 5.0V systems due to TTL-compatible inputs
• Buffering signals in high-speed data transmission interfaces
• Clock signal generation and conditioning in microcontroller systems

Inverter Gates Procurement Notes

Verify the specific manufacturer lot and date code upon receipt, as Fairchild Semiconductor products may be distributed by various authorized partners. Confirm that the received components match the exact 74VHCT04AMX designation, noting that suffixes can indicate packaging variations or specific manufacturing runs. Ensure compliance with RoHS standards if required for your assembly process. Cross-reference the datasheet revision number to confirm electrical parameters align with your design specifications before integration.

Inverter Gates Selection Notes

Select this component when TTL-compatible input thresholds are required alongside CMOS low-power benefits. The VHCT series bridges the gap between standard HC/HCT logic and faster VHC/VHCT families. Consider the 14-SOIC package constraints for PCB layout. This part is suitable for applications needing robust noise immunity and defined output drive capabilities without the higher cost of bipolar technologies. Evaluate thermal management requirements based on the specified operating temperature range.

Inverter Gates Part Context

The 74VHCT04AMX belongs to the VHCT family of high-speed CMOS logic devices produced by Fairchild Semiconductor. This series is designed to offer performance improvements over the standard 74HCT04 while remaining pin-compatible. The 'M' suffix typically denotes the SOIC-14 surface-mount package, and 'X' often indicates tape-and-reel packaging for automated assembly. It is part of a broader ecosystem of VHCT inverters and buffers used in industrial and consumer electronics.

Inverter Gates Replacement Considerations

The 74VHCT04AMTCX is a verified equivalent from the same manufacturer family, differing primarily in the TSSOP-14 package instead of SOIC-14. Other manufacturers such as ON Semiconductor and STMicroelectronics produce functionally identical parts like the MC74VHCT04A and HCC4069UB respectively, though pinouts and specific electrical limits should be cross-checked against the original datasheet.
