74HCT04D,653

Overview

The Nexperia 74HCT04D,653 is a hex inverter integrated circuit belonging to the 74HCT logic family. It contains six independent inverters housed in a 14-lead plastic small outline package (SO14, SOT108-1). The device operates with a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. Static characteristics specify a maximum propagation delay of 29 ns at 4.5 V and 40 µA maximum supply current at 5.5 V.

Feature Summary

• Accepts TTL-level input signals while utilizing CMOS technology for low power dissipation.
• Includes input clamp diodes to facilitate interfacing with voltages exceeding the supply rail using current limiting resistors.
• Provides high noise immunity and robust latch-up performance compliant with JESD 78 Class II Level B standards.

Applications

• Signal inversion within digital logic circuits
• Waveform generation and shaping
• Clock signal buffering

Procurement Notes

Verify that the component matches the specific 74HCT04D,653 designation to ensure correct HCT logic compatibility rather than HC variants. Confirm the SO14 package type aligns with board layout requirements. Check datasheet revisions for any updates to ESD specifications or operating conditions prior to final design approval.

Selection Notes

Select this component when TTL-compatible inputs are required alongside CMOS output drive capabilities. The wide operating temperature range makes it suitable for industrial environments. Ensure the application does not exceed the absolute maximum ratings for supply voltage or output current to prevent permanent damage.

Part Context

This part is manufactured by Nexperia USA Inc. and falls under the broader 74HCT04 product line. It is designed as a direct replacement for similar hex inverters from other manufacturers, maintaining pinout and functional compatibility with standard 74-series logic families.

Replacement Considerations

Equivalent parts include the SN74HCT04N from Texas Instruments and the MC74HCT04ADWR2 from onsemi. Verify package dimensions and electrical parameters against the original design requirements before substitution.

FAQ

What is the difference between the 74HC04 and 74HCT04 input levels?

The 74HC04 accepts CMOS-level input signals, whereas the 74HCT04 is designed to accept TTL-level input signals, allowing for direct interfacing with TTL outputs.

How does the device handle input voltages higher than VCC?

The inputs include clamp diodes that enable the use of current-limiting resistors to interface inputs to voltages in excess of VCC without damaging the device.
