SN74AHCT04PW

Overview

The SN74AHCT04PW is a hex inverter integrated circuit manufactured by Texas Instruments. It belongs to the 74AHCT logic series, utilizing CMOS technology with TTL-compatible inputs. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a wide operating temperature range from -40°C to +125°C. It features six independent inverters housed in a 14-pin TSSOP package. Key electrical characteristics include a typical propagation delay of 6.7 ns at 5 V and an output current capability of ±8 mA.

Feature Summary

• TTL-compatible input levels allow direct interfacing with 5V TTL logic systems without level shifting requirements.
• High-speed operation ensures low propagation delay for efficient signal inversion in digital circuits.
• Robust drive capability provides sufficient output current for standard logic loads.
• Extended temperature rating supports reliable performance in industrial and commercial environments.

Applications

• Signal inversion in 5V digital logic systems
• Clock signal conditioning and buffering
• Interface between TTL and CMOS logic families

Procurement Notes

Verify the exact part number SN74AHCT04PW against manufacturer datasheets to confirm pinout and electrical specifications. Ensure the TSSOP-14 package matches your PCB footprint requirements. Check RoHS compliance status if environmental regulations apply to your assembly process. Confirm that the 4.5V to 5.5V supply voltage range aligns with your system power design.

Selection Notes

Select this component when TTL-compatible inputs are required alongside CMOS low-power benefits. The AHCT series bridges the gap between older TTL standards and modern CMOS processes. Consider the 125°C maximum operating temperature for applications exceeding standard commercial ranges. Evaluate the 6.7 ns propagation delay against your system timing constraints to ensure adequate speed performance.

Part Context

This device is part of the broader 74-series logic family, specifically the Advanced High-Speed CMOS Technology (AHCT) line. It serves as a fundamental building block for digital logic designs requiring hex inverters. The PW suffix denotes the TSSOP surface-mount package, distinguishing it from through-hole or other surface-mount variants like the PWR reel version.

Replacement Considerations

Direct substitutes include SN74AHCT04PWR and SN74AHCT04BQAR, provided the package type (TSSOP vs WQFN) and supply voltage compatibility are verified. Cross-manufacturer equivalents such as MC74VHCT04 may require careful evaluation of input/output electrical characteristics and pinout alignment before integration.
