CD4013BCSJ

Overview

The CD4013BCSJ is a dual D-type flip-flop integrated circuit from the 4000 series, manufactured by Fairchild Semiconductor. It contains two independent positive edge-triggered D flip-flops with complementary Q and Q outputs. The device features asynchronous set and reset inputs that operate independently of the clock signal. Constructed using complementary MOS (CMOS) technology, it supports a wide supply voltage range of 3.0V to 15V and offers high noise immunity.

Procurement Notes

Verify the manufacturer origin as Fairchild Semiconductor or its successor entities, noting that acquisition history may affect part marking. Confirm the package type matches the specific suffix requirements for your assembly process. Ensure the component meets current environmental compliance standards relevant to your region. Cross-reference datasheet revisions to confirm pinout and electrical characteristics remain consistent with your design specifications.

Selection Notes

Select this component when designing circuits requiring dual storage elements in a single package. It is suitable for low-power CMOS logic designs operating within the specified voltage range. Consider its compatibility with TTL loads if interfacing with legacy systems. Evaluate the noise immunity requirements against the typical specification for your operating environment.

Part Context

This component belongs to the standard 4000 series CMOS logic family, widely used in general-purpose digital logic applications. It serves as a fundamental building block for sequential logic circuits. The dual configuration allows for compact design in applications requiring multiple bits of storage or counting functions without consuming excessive board space.

Replacement Considerations

Compatible substitutes include the CD4013B from Texas Instruments and HEF4013BT from Nexperia. Verify pin compatibility and electrical parameters before substitution. Ensure the replacement package matches the original footprint.
