SN74HC04DBRG4

Overview

The SN74HC04DBRG4 is a hex inverter integrated circuit manufactured by Texas Instruments, belonging to the SN74HC series of CMOS logic devices. It contains six independent inverters within a single package. The device operates with a supply voltage range of 2 V to 6 V and supports surface-mount installation in a 14-pin SOIC package. Key electrical parameters include a maximum propagation delay of 20 ns, a high-level output current of -4 mA, and a low-level output current of 4 mA. It functions reliably across an operating temperature range from -40 °C to +85 °C.

Feature Summary

• Contains six independent inverter circuits for signal inversion applications
• CMOS technology ensures low power consumption and high noise immunity
• Compatible with standard TTL logic levels at specified voltages

Applications

• Digital signal inversion in logic circuits
• Clock signal generation and shaping
• General-purpose switching applications

Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and lead-free status as per Texas Instruments documentation. Confirm the package type is SOIC-14 and the reel quantity matches procurement requirements. Ensure the operating temperature range meets system specifications. Cross-reference the manufacturer part number with official TI databases to confirm active status and availability.

Selection Notes

Select this component when six independent inverters are required in a compact surface-mount form factor. The HC series offers compatibility with 2V to 6V supply rails, suitable for various digital logic families. Consider the 20 ns propagation delay for timing-critical designs. Verify that the SOIC-14 package fits the PCB footprint constraints and thermal management requirements of the target application.

Part Context

This component is part of the broader SN74HC04 family, which includes variants with different packaging options such as PDIP and SSOP. The 'D' suffix denotes the SOIC package, while 'G4' typically signifies environmental compliance features like lead-free construction. It serves as a fundamental building block in digital electronics for creating NOT gates and signal conditioning stages.

Replacement Considerations

Direct pin-compatible alternatives within the same family include SN74HC04DR and SN74HC04DRE4. For enhanced performance, consider the SN74AHC04 series, though voltage ranges and speed characteristics may differ. Always verify electrical specifications and package dimensions before substitution.
