SN74HC04DBRE4

Overview

The SN74HC04DBRE4 is a hex inverter integrated circuit manufactured by Texas Instruments, belonging to the SNx4HC04 series. It utilizes advanced CMOS technology and features six independent inverters within a single package. The device operates within 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 parameters 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 SOIC package and is supplied in tape and reel packaging.

Feature Summary

• Contains six independent inverter channels for signal inversion applications
• Advanced CMOS technology ensures low power consumption and high noise immunity
• Compatible with standard TTL logic input levels despite CMOS construction
• Wide operating voltage range supports diverse system power requirements

Applications

• General-purpose digital signal inversion in consumer electronics
• Clock signal generation and shaping in timing circuits
• Interface buffering between different logic families
• Memory address decoding and data line inversion

Procurement Notes

Verify the complete part number including the E4 suffix to confirm lead-free status and RoHS compliance. Ensure the SOIC-14 package type matches your PCB footprint requirements. Confirm that the tape and reel packaging aligns with your automated assembly equipment specifications. Check for any specific environmental or export control classifications if applicable to your region.

Selection Notes

Select this component when six independent inverters are required in a surface-mount design. The HC series offers a balance of speed and power consumption suitable for general digital logic. Consider the 2 V to 6 V operating range to ensure compatibility with your system's supply voltage. Verify that the 20 ns propagation delay meets your timing constraints for the intended application frequency.

Part Context

This device is part of the Texas Instruments SNx4HC04 family of hex inverters. It shares functional characteristics with other variants in the series but differs in package style and packaging format. The DBRE4 designation specifically indicates an SOIC-14 package with lead-free composition and tape-and-reel delivery. It serves as a direct replacement for older non-compliant versions while maintaining pinout compatibility.
