74HCT04N,652

Overview

The 74HCT04N,652 is a hex inverter manufactured by Nexperia. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. The device features TTL-level input compatibility and includes clamp diodes on inputs for interfacing with voltages exceeding VCC. Static characteristics specify a maximum low-level output voltage of 0.4 V at 5.2 mA load and a high-level output voltage of 3.7 V at -4.0 mA load. Dynamic performance under a 50 pF load shows a propagation delay of up to 29 ns and a transition time of up to 22 ns.

Feature Summary

• Hex inverter configuration providing six independent logic inversion channels
• TTL-level input compatibility ensuring direct interface with standard logic families
• Input clamp diodes enable safe interfacing with voltages exceeding the supply rail

Applications

• Signal level translation between different logic families
• Clock signal buffering and inversion
• Logic state inversion in digital control circuits

Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the base part number covers multiple physical packages. Confirm the manufacturer designation aligns with current corporate branding, as production may be managed by Nexperia rather than NXP USA Inc. Ensure the component meets the specified operating temperature range for the intended application environment before finalizing procurement.

Selection Notes

Select this component when TTL-compatible inputs are required alongside CMOS noise immunity. The HCT series ensures compatibility with legacy 5 V logic systems while offering improved power dissipation characteristics compared to older bipolar technologies. Verify that the chosen package variant fits the available board space and thermal requirements of the design.

Part Context

This component belongs to the 74HCT logic family, which bridges the gap between HC CMOS technology and traditional TTL standards. The '04' designation indicates a hex inverter function. While originally developed under the NXP brand, the standard product business was transferred to Nexperia, which now manufactures and documents these devices according to updated specifications.

Replacement Considerations

Direct functional replacements include other 74HCT04 variants from manufacturers such as Texas Instruments (e.g., SN74HCT04), ON Semiconductor, or STMicroelectronics. Ensure any substitute maintains the same 14-pin package footprint and pinout configuration to guarantee mechanical and electrical compatibility.
