4076BDCQR

Overview

The DM4076BDCQR is a high-speed CMOS logic gate manufactured by National Semiconductor, now part of Texas Instruments. It functions as a hex inverter within the 4000B series of integrated circuits. The device utilizes standard complementary metal-oxide-semiconductor technology to provide six independent inverting gates in a single package. It is designed for operation across a wide supply voltage range typical of the 4000B CMOS family. The component is housed in a surface-mount plastic dual in-line package with fourteen pins, suitable for automated assembly processes.

Feature Summary

• Contains six independent inverting logic gates
• Utilizes high-speed CMOS technology
• Operates over a wide supply voltage range
• Available in a fourteen-pin surface-mount package

Applications

• General-purpose digital signal inversion
• Clock signal generation and shaping
• Logic level translation between stages
• Combinational logic circuit implementation

Procurement Notes

Verify the manufacturer marking on the component body to confirm National Semiconductor or Texas Instruments origin. Ensure the suffix matches the specified DCQR designation for the correct package type and tape-and-reel configuration. Cross-reference the date code against current production status to avoid obsolete stock. Confirm that the device meets the required environmental specifications for the intended application environment.

Selection Notes

Select this component when a hex inverter function is required in a compact surface-mount form factor. Consider the 4000B series characteristics regarding noise immunity and power consumption relative to other logic families. Evaluate the operating voltage requirements of the system to ensure compatibility with the CMOS input thresholds. Assess the pin count and package dimensions against the available board space constraints.

Part Context

This component belongs to the 4000B series of CMOS logic devices, which are widely used in digital electronics. The 4000B series offers improved performance over earlier iterations, including higher speed and better noise margins. National Semiconductor was a primary producer of these logic families before its acquisition by Texas Instruments, which continues to support the product line.

Replacement Considerations

Equivalent parts include the SN74HC04 or SN74HCT04 from Texas Instruments for similar hex inverter functionality in different logic families. Other manufacturers such as ON Semiconductor or STMicroelectronics offer compatible hex inverters in comparable packages. Verify pin compatibility and electrical parameters before substitution.
