74HC04D/AUJ

Overview

The 74HC04D/AUJ is a hex inverter manufactured by Nexperia, housed in an SO14 (SOT108-1) plastic small outline package with 14 leads. It operates on a supply voltage range of 2.0 V to 6.0 V and complies with JEDEC standard no. 7A. The device features CMOS low power dissipation and high noise immunity. Static characteristics include input leakage current up to ±1 μA at 6.0 V and supply current up to 40 μA at -40 °C to +125 °C. Dynamic performance specifies propagation delay times ranging from 14 ns to 22 ns at 6.0 V across the extended temperature range.

Feature Summary

• Includes clamp diodes on inputs to allow interfacing with voltages exceeding VCC using current limiting resistors.
• Latch-up performance exceeds 100 mA per JESD 78 Class II Level B.
• ESD protection meets ANSI/ESDA/JEDEC JS-001 class 2 for HBM exceeding 2000 V and JS-002 class C3 for CDM exceeding 1000 V.

Applications

• General purpose logic inversion
• Signal buffering
• Clock signal generation

Procurement Notes

Verify the specific ordering code against the manufacturer's official documentation to ensure correct package type and temperature rating. Confirm that the component matches the required JEDEC compliance standards for your design. Check for any recent revision history updates that may affect pinning or electrical specifications before finalizing procurement orders.

Selection Notes

Select this component when a hex inverter compatible with LSTTL pinouts is required within a wide voltage range. Consider the SO14 package for through-hole mounting requirements. Ensure the application environment stays within the specified -40 °C to +125 °C operating temperature range to maintain guaranteed dynamic and static performance levels.

Part Context

This part belongs to the 74HC series of high-speed silicon-gate CMOS logic devices. It is designed to be pin-compatible with low-power Schottky TTL (LSTTL) families, facilitating direct replacement in legacy designs. The device adheres to JEDEC standard no. 7A, ensuring interoperability with other components from various manufacturers within the same logic family ecosystem.

Replacement Considerations

Direct replacements include the 74HCT04D for TTL-level input compatibility. Other hex inverters from the 74HC family may serve as functional substitutes if pinout and voltage specifications align.

FAQ
