4007UBDC

Overview

The CD4007UBDC is a CMOS integrated circuit from the 4000 series, manufactured by National Semiconductor. It contains two complementary pairs of N-channel and P-channel enhancement-mode MOSFETs along with one inverter. The device is housed in a 14-pin ceramic dual in-line package (DIP). It operates within a supply voltage range of 3V to 15V and supports an operating temperature range of -55°C to +125°C.

Feature Summary

• Contains two fully independent complementary MOSFET pairs for flexible circuit configuration
• Includes a dedicated inverter gate for signal inversion applications
• Utilizes standard CMOS technology compatible with TTL logic levels

Applications

• General-purpose switching circuits requiring complementary output stages
• Test equipment and laboratory instrumentation for component characterization
• Educational modules for demonstrating MOSFET operation principles

Procurement Notes

Verify the specific manufacturer origin, as National Semiconductor assets are now managed by Texas Instruments. Confirm that the ceramic DIP package matches the required environmental specifications for military or high-reliability applications. Ensure the part number suffix corresponds to the correct pinout and material composition defined in the official datasheet.

Selection Notes

Select this component when a single package provides multiple complementary MOSFET pairs and an inverter. It is suitable for designs requiring high input impedance and low static power consumption. Consider the ceramic package for superior thermal stability compared to plastic variants in harsh environments.

Part Context

This device belongs to the widely used 4000 series of CMOS digital logic components. It serves as a versatile building block for analog and digital hybrid circuits. The inclusion of both N-channel and P-channel devices allows for the creation of push-pull outputs without external discrete components.
