74HCT04D

Overview

The 74HCT04D is a hex inverter integrated circuit manufactured by Toshiba Semiconductor and Storage. It belongs to the 74HCT logic series, designed for operation with a supply voltage range of 4.5V to 5.5V. The device features six independent inverting channels within a 14-pin SOIC package. Key electrical characteristics include a maximum propagation delay of 8ns at 5V and output drive currents of 4mA for both high and low states. It operates reliably across a temperature range of -40°C to +85°C.

Feature Summary

• CMOS technology providing TTL-compatible input levels
• Six independent inverting channels per package
• High noise immunity with stable output performance

Applications

• Signal inversion in digital logic circuits
• Clock signal conditioning
• Buffering between TTL and CMOS logic stages

Procurement Notes

Verify the specific suffix against official Toshiba documentation to confirm pinout and electrical specifications. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit products. Confirm that the operating voltage range aligns with your system design constraints before procurement.

Selection Notes

Select this component when TTL-compatible inputs are required with CMOS low power consumption. The 74HCT series bridges the gap between older TTL systems and modern CMOS designs. Consider the 14-SOIC package size for surface mount applications. Verify that the 4.5V to 5.5V supply range matches your power distribution network.

Part Context

This part is part of the broader 74HCT logic family produced by Toshiba. It serves as a direct functional replacement for other manufacturers' 74HCT04 equivalents. The device is widely used in general-purpose digital electronics where reliable inversion and level shifting are necessary.

Replacement Considerations

Compatible substitutes include 74HCT04 from NXP, STMicroelectronics, or ON Semiconductor. Verify pin compatibility and electrical parameters before substitution.
