74HCT04BQ,115

Overview

The 74HCT04BQ,115 is a hex inverter manufactured by Nexperia USA Inc., belonging to the 74HCT logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL-compatible input levels. The device provides six independent inverters with clamp diodes on inputs for overvoltage interfacing. It is housed in a 14-terminal DHVQFN package (SOT762-1) measuring 2.5 mm x 3 mm x 0.85 mm. The component supports an ambient operating temperature from -40 °C to +125 °C and includes ESD protection exceeding 2000 V (HBM).

Feature Summary

• CMOS low power dissipation with high noise immunity.
• TTL input levels compatible with standard digital logic systems.
• Integrated input clamp diodes allow interfacing to voltages exceeding VCC using current limiting resistors.
• Robust latch-up performance exceeding 100 mA per JESD 78 Class II Level B.

Applications

• Signal inversion in digital logic circuits.
• Waveform generation and shaping.
• Clock signal buffering and conditioning.

Procurement Notes

Verify the specific ordering suffix

Selection Notes

Select this component when TTL-level compatibility is required at 5 V operation. The DHVQFN package offers space efficiency for dense PCB layouts. Ensure thermal management accounts for the specified total power dissipation derating curves above 98 °C. Confirm that the application does not require automotive qualification, as this product is not designated for such use.

Part Context

This part belongs to the 74HCT04 series, which defines a hex inverter function. The 'BQ' suffix indicates the DHVQFN14 leadless package variant. It shares functional characteristics with other 74HCT04 packages like SO14 and TSSOP14 but differs in physical dimensions and thermal properties. The datasheet revision 10 was released in February 2024.

Replacement Considerations

Direct pin-to-pin replacements include other manufacturers' 74HCT04 devices in equivalent DHVQFN14 packages. Verify logic level compatibility and electrical specifications against the original requirements before substitution.

FAQ

What is the recommended operating supply voltage range?

The recommended operating supply voltage (VCC) range is 4.5 V to 5.5 V.

How does the device handle input voltages higher than VCC?

The inputs include clamp diodes, enabling the use of current limiting resistors to interface inputs to voltages in excess of VCC.

What is the maximum propagation delay at 4.5 V?

At VCC = 4.5 V with CL = 50 pF, the maximum propagation delay is 29 ns across the full temperature range of -40 °C to +125 °C.
