SN74HC04DBR

Overview

The SN74HC04DBR 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 a wide operating temperature range from -40°C to +85°C. Key electrical specifications include a propagation delay of 20 ns at 5 V with 50 pF load, high-level output current of -4 mA, and low-level output current of 4 mA. It is housed in a 14-pin SSOP (Small Outline Small Package) surface-mount package.

Feature Summary

• Contains six independent inverting channels for signal inversion applications
• CMOS technology ensures low power consumption and high noise immunity
• Compatible with standard TTL logic levels across the specified voltage range
• Surface-mount SSOP packaging facilitates automated PCB assembly

Applications

• General-purpose digital signal inversion in consumer electronics
• Clock signal generation and shaping in microcontroller circuits
• Logic level translation between different voltage domains
• Buffering and driving loads in industrial control systems

Procurement Notes

Verify the specific suffix 'DBR' corresponds to the SSOP-14 package and tape-and-reel quantity when ordering. Confirm RoHS compliance status as per the latest manufacturer datasheet revision. Ensure the supplier provides traceability documentation for automotive or industrial grade requirements if applicable. Check for any recent product change notifications regarding pinout or electrical characteristics updates.

Selection Notes

Select this component when a hex inverter function is required in a compact surface-mount form factor. The HC series offers a balance of speed and power consumption suitable for general digital logic. Consider the SSOP package dimensions against available PCB real estate. Verify that the 2V to 6V operating range aligns with the system's power supply rails. Compare propagation delay specifications against timing requirements of the target application.

Part Context

The SN74HC04 is part of Texas Instruments' extensive 74HC logic family, which utilizes high-speed CMOS technology. This family is designed to be compatible with standard TTL inputs while offering lower power dissipation than older LS series devices. The DBR suffix specifically denotes the SSOP-14 package variant, distinguishing it from DIP or SOIC versions within the same logical function family.

Replacement Considerations

• SN74HC04DR: Same logic function but in SOIC-14 package
• SN74HC04DRE4: RoHS-compliant version of the SOIC-14 variant
• SN74HC04N: PDIP-14 through-hole equivalent for prototyping
