Overview
The 4001BDMQB is a quad 2-input NOR gate integrated circuit manufactured by National Semiconductor. It belongs to the 4000/14000/40000 series of logic devices and is housed in a 14-pin ceramic dual in-line package (CDIP). The component operates within a temperature range of -40 °C to 85 °C and supports power supplies of 5 V or 15 V. It features a load capacitance of 50 pF and contains four independent NOR gates, each with two inputs.
Feature Summary
- Quad configuration providing four independent 2-input NOR logic functions
- Robust ceramic dual in-line packaging suitable for high-reliability environments
- Wide operating temperature range supporting industrial applications
Applications
- Industrial automation systems
- Signal conditioning circuits converting analog signals to digital formats
- General-purpose logic processing in embedded systems
Procurement Notes
Verify that the specific part number matches the CDIP package variant, as the 4001 series is available in multiple package types including plastic DIP and SOIC. Confirm the manufacturer origin, noting that National Semiconductor assets were acquired by Texas Instruments, which may affect sourcing channels and documentation availability. Ensure compatibility with existing board layouts designed for 14-lead ceramic packages.
Selection Notes
Select this component when high reliability and radiation hardness are required, as indicated by the ceramic construction. It is appropriate for designs needing standard NOR logic functionality within the 4000 series voltage ranges. Consider alternative plastic packages if cost reduction is prioritized over environmental robustness, provided the thermal and mechanical requirements allow.
Part Context
This device is part of the extensive 4000 series CMOS logic family, known for wide supply voltage flexibility. National Semiconductor was a prominent manufacturer before its acquisition by Texas Instruments. The 4001BDMQB specifically denotes the ceramic package version, distinguishing it from the more common plastic variants like the CD4001BCJ.
Replacement Considerations
The CD4001BCJ serves as a functional equivalent but utilizes a plastic DIP package rather than ceramic. Verify pinout compatibility and ensure the replacement package fits the physical constraints of the target application.
