CD4006BK/3

Shift Registers Overview

The CD4006BK/3 is a CMOS logic integrated circuit belonging to the 4000 series, manufactured by Harris Corporation. It functions as a Serial In Serial Out shift register with a 5-bit depth and right-direction data shifting capability. The device features true outputs and utilizes a shared clock mechanism across four internal shift registers, which are configured as two 4-bit and two 5-bit units. It operates within a supply voltage range of 5V to 15V and supports a maximum frequency of 2.5 MHz at nominal supply conditions. The component is housed in a 14-pin Ceramic Dual In-Line Package (CDIP) designed for through-hole mounting.

Shift Registers Feature Summary

• Serial In Serial Out architecture with 5-bit shift register depth
• Shared clock distribution across multiple independent shift register sections
• CMOS construction ensuring compatibility with standard logic families
• True output polarity providing direct signal inversion-free transmission

Shift Registers Applications

• Digital data storage and temporary buffering in serial communication systems
• Time-delay generation circuits utilizing sequential bit shifting
• Parallel-to-serial or serial-to-parallel conversion interfaces
• Basic arithmetic operations such as multiplication and division in digital processors

Shift Registers Procurement Notes

Verify that the specific part number matches the ceramic package variant rather than plastic DIP alternatives. Confirm RoHS compliance status as older Harris manufacturing runs may not meet current environmental standards. Ensure the supplier provides documentation confirming the 5V to 15V operating range and 2.5 MHz frequency limit. Check for any manufacturer obsolescence notices or lifecycle status updates prior to finalizing procurement orders.

Shift Registers Selection Notes

Select this component when a robust ceramic package is required for high-temperature environments exceeding standard plastic limits. Choose this part over plastic variants if long-term reliability in harsh industrial conditions is critical. Consider the shared clock feature for designs requiring synchronized operation of multiple shift stages without complex external gating logic.

Shift Registers Part Context

This component is part of the extensive 4000 series of CMOS logic devices originally developed for general-purpose digital applications. The 4006 specifically addresses the need for multi-stage shift registers within a single integrated circuit. Its design allows for flexible configuration of bit depths, making it a versatile building block for various digital signal processing tasks compared to fixed-width alternatives.

Shift Registers Replacement Considerations

Direct substitutes include other 4000-series shift registers like the CD4094, though pinouts and functionality differ. Verify compatibility with existing board layouts when considering plastic DIP replacements such as the CD4006BD3.
