40014BDM

Overview

The CD4014BM is an 8-stage static shift register manufactured by National Semiconductor. It belongs to the 4000/14000/40000 series of CMOS logic devices. The component operates within a temperature range of -55 °C to 125 °C and features a ceramic glass-sealed DIP-16 package. Key electrical characteristics include a maximum quiescent current of 30 µA and a load capacitance of 50 pF. The device supports serial-in parallel-out functionality with synchronous operation.

Feature Summary

• Provides eight-stage static shift register capability for data storage and transfer
• Operates reliably across extended industrial temperature ranges up to 125 °C
• Utilizes low-power CMOS technology with minimal quiescent current consumption
• Constructed in a durable ceramic glass-sealed dual in-line package

Applications

• Serial-to-parallel data conversion circuits
• Digital signal processing interfaces requiring data buffering
• Industrial control systems operating in harsh thermal environments
• Embedded memory modules for temporary data retention

Procurement Notes

Verify the specific suffix 'BDM' against official National Semiconductor or Texas Instruments documentation to confirm package type and material composition. Ensure compatibility with existing PCB footprints for the CDIP-16 ceramic variant. Confirm RoHS status as the provided data indicates non-compliance, which may affect regulatory approval for certain markets. Validate supply chain authenticity through authorized distributors.

Selection Notes

Select this component when high-temperature stability and robust packaging are required for shift register applications. The ceramic construction offers superior durability compared to plastic packages in extreme conditions. Consider the 30 µA quiescent current limit for power-sensitive designs. Verify that the 8-stage capacity meets system requirements without necessitating cascading multiple units.

Part Context

This part belongs to the extensive 4000/14000/40000 series of CMOS logic integrated circuits originally developed by National Semiconductor, now under Texas Instruments. These components are widely recognized for their compatibility with standard TTL logic levels and broad operating voltage ranges. The CD4014BM specifically addresses needs for reliable serial data handling in demanding industrial and commercial environments.

Replacement Considerations

Cross-reference with other CD4014 variants from Texas Instruments or onsemi for pin-compatible alternatives. Verify functional equivalence regarding shift register architecture and electrical specifications before substitution.
