74HC04DB,118

Overview

The Nexperia 74HC04DB,118 is a hex inverter integrated circuit belonging to the 74HC CMOS logic family. It contains six independent inverters housed in a 14-lead plastic small outline package (SO14), designated as SOT108-1. The device operates within a supply voltage range of 2.0 V to 6.0 V and supports an ambient temperature range from -40 °C to +125 °C. Static characteristics specify high-level input voltage thresholds between 1.5 V and 4.2 V depending on supply conditions, with low-level input voltages up to 1.8 V. Propagation delay ranges from 130 ns at 2.0 V to 22 ns at 6.0 V under standard load conditions.

Feature Summary

• CMOS technology providing low power dissipation and high noise immunity
• Inputs include clamp diodes for interfacing with voltages exceeding VCC
• ESD protection exceeds 2000 V according to Human Body Model standards

Applications

• Signal inversion in digital logic circuits
• Clock signal generation and conditioning
• Level shifting interfaces utilizing clamp diode inputs

Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature grade. Confirm that the component version aligns with current production status rather than obsolete specifications. Ensure compliance with RoHS directives and JEDEC standards relevant to the target application environment before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring multiple independent signal inversions within a single package footprint. The wide supply voltage compatibility allows operation across various digital logic domains. Consider the propagation delay specifications relative to the system clock speed requirements to ensure timing margins are met during high-frequency operations.

Part Context

This part belongs to the broader 74HC series of high-speed CMOS logic devices manufactured by Nexperia. The 'DB' designation specifically identifies the SO14 surface-mount package variant. This series is widely utilized in general-purpose digital electronics for basic logic functions, offering a balance of performance and power efficiency suitable for consumer and industrial applications.

Replacement Considerations

Compatible substitutes include other manufacturers' 74HC04 variants in SOIC-14 packages. Verify pinout compatibility and electrical parameter equivalence, particularly regarding propagation delay and output drive capability, before implementing any cross-brand replacements.
