74HCT08D,652

Overview

The Nexperia 74HCT08D,652 is a quad 2-input AND gate from the HCT logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range of -40 °C to +125 °C. The device features TTL-level input compatibility and CMOS low power dissipation. It is housed in a SO14 plastic small outline package (SOT108-1) with a body width of 3.9 mm. Static characteristics include a maximum propagation delay of 36 ns at 4.5 V and a typical input leakage current of ±1 μA at 5.5 V.

Feature Summary

• TTL-compatible input levels for direct interfacing with standard logic families
• CMOS technology providing low power dissipation
• High noise immunity suitable for demanding environments
• Robust latch-up performance exceeding JESD 78 Class II Level B

Applications

• Digital logic circuits requiring AND operations
• Signal gating and data routing applications
• General-purpose logic systems operating at 5 V

Procurement Notes

Verify component authenticity through authorized distributors or official Nexperia channels. Confirm the specific suffix '652' corresponds to the tube packaging format. Ensure compliance with RoHS directives and check for any recent product change notices affecting specifications or manufacturing locations before finalizing procurement plans.

Selection Notes

Select this component when TTL-level inputs are required alongside CMOS output drive capabilities. The wide operating temperature range makes it suitable for industrial applications. Verify that the SO14 package dimensions fit the target PCB layout constraints. Consider the propagation delay specifications relative to the system clock speed requirements.

Part Context

This part belongs to the 74HCT series, which bridges HC CMOS performance with TTL input compatibility. The 'D' designation indicates the SO14 surface-mount package. The '652' suffix typically denotes tube packaging. This series is widely used in digital electronics for basic logic functions where reliable switching and standard voltage levels are necessary.

Replacement Considerations

Check for 74HCT08D,653 if reel packaging is preferred over tubes. Verify pinout compatibility with other 74HCT08 variants from different manufacturers. Ensure replacement parts meet the same temperature and voltage specifications.
