4035BDC

Overview

The CD4035BDC is a 4-bit parallel-in/parallel-out shift register manufactured by National Semiconductor. It utilizes complementary MOS (CMOS) technology and is housed in a 16-pin ceramic dual in-line package (CDIP). The device supports bidirectional data shifting and features configurable outputs. It operates within a supply voltage range of 5 V to 15 V and is qualified for military standards, specifically MIL-STD-883 Class C, ensuring functionality across an extended temperature range from -55 °C to 125 °C.

Feature Summary

• Monolithic CMOS construction using P- and N-channel devices
• Configurable output polarity for flexible logic interfacing
• Military-grade qualification compliant with MIL-STD-883 Class C
• Bidirectional shifting capability for versatile data handling

Applications

• Parallel-to-parallel data transfer systems
• Military aerospace electronic circuits
• High-reliability industrial control logic
• Data storage and buffering modules

Procurement Notes

Verify the specific suffix 'DC' indicates the ceramic DIP package variant. Confirm MIL-STD-883 Class C screening requirements are met for your application. Ensure supply voltage limits between 5 V and 15 V are respected. Check lead composition compliance if RoHS exemptions apply. Validate operating temperature ranges against environmental conditions.

Selection Notes

Select this component when high reliability and radiation hardness are required. The ceramic package offers superior thermal stability compared to plastic variants. Consider the bidirectional feature if data flow direction changes dynamically. Ensure the 16-pin footprint matches the PCB layout constraints. Verify that the CMOS input thresholds align with the driving logic levels.

Part Context

This part belongs to the standard 4000-series CMOS logic family. It serves as a specialized shift register variant distinct from general-purpose flip-flops. The military grade designation differentiates it from commercial counterparts like the CD4035BC. It provides a robust solution for harsh environment applications where standard commercial parts may fail.

Replacement Considerations

HEC4035BD by NXP is a documented equivalent offering similar 4-bit parallel-in/parallel-out functionality in a ceramic DIP package. Both parts share the 4000-series CMOS architecture and military temperature ratings. Verify pinout compatibility before substitution.
