SN74AHCT04PWG4

Overview

The SN74AHCT04PWG4 is a hex inverter integrated circuit manufactured by Texas Instruments. It features six independent inverters within a single package, utilizing advanced CMOS technology to deliver high-speed performance with low power consumption. The device operates across a wide voltage range of 2V to 5.5V and supports TTL-compatible input levels, facilitating seamless interfacing between 3.3V and 5V logic systems. Packaged in a 14-pin TSSOP format, it ensures robust electrostatic discharge protection and latch-up immunity exceeding 250mA per JESD 17 standards.

Feature Summary

• TTL-compatible input thresholds allow direct connection to 5V logic systems while operating at lower voltages.
• Advanced CMOS construction provides high-speed operation with minimal static power dissipation.
• Robust ESD protection meets stringent industry standards for human model and charged device model testing.

Applications

• Level shifting interfaces between 3.3V and 5V digital logic domains
• Signal inversion in high-speed data processing circuits
• Clock signal conditioning and buffering

Procurement Notes

Verify the suffix G4 indicates RoHS compliance and lead-free composition as per Texas Instruments specifications. Confirm the package designation PW corresponds to the 14-lead Thin Shrink Small Outline Package (TSSOP). Ensure the ordering part number matches the specific speed grade and temperature rating required for your application design constraints.

Selection Notes

Select this component when TTL-level compatibility is required alongside low-power CMOS performance. It serves as an optimal interface solution for bridging 5V legacy systems with modern 3.3V or 2.5V logic families. Consider its propagation delay characteristics relative to system timing requirements and ensure the thermal management strategy accommodates the specified operating temperature range.

Part Context

This component belongs to the SN74AHC/U/V/HCT series of high-speed CMOS logic devices from Texas Instruments. These parts are designed for applications demanding fast switching speeds and low power consumption. The AHCT variant specifically bridges the gap between standard CMOS inputs and TTL-compatible logic levels, making it versatile for mixed-voltage digital designs.

Replacement Considerations

SN74AHCT04PWR is the non-RoHS compliant equivalent. SN74AHCT04PW is the base part number without the manufacturing suffix. Verify pinout compatibility before substitution.
