CD4024BCN Binary Counter 7-Bit Logic IC Equivalent & Substitute Parts

Part Overview

The CD4024BCN is a 7-bit binary counter logic IC manufactured by onsemi, housed in a 14-MDIP package. This component functions as a negative edge-triggered counter with asynchronous reset capability, operating across a wide voltage range of 3V to 15V and temperature range of -55°C to 125°C. The CD4024BCN is classified as obsolete, making identification of active equivalent parts essential for new designs and production continuity. The CD4024 base product series remains in active production through alternative manufacturers, enabling direct functional substitution while maintaining circuit compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD4024BCN is determined by strict equivalence across the following critical parameters:

• Logic Type & Function: Binary counter with identical 7-bit configuration and single element
• Trigger Characteristics: Negative edge-triggered operation with asynchronous reset
• Package Compatibility: 14-DIP through-hole form factor with 0.300" (7.62mm) pitch
• Electrical Specifications: Supply voltage range, operating temperature range, and count rate capability
• Base Product Series: CD4024 family designation ensuring pin-compatible functionality

The CD4024BE from Texas Instruments qualifies as a direct substitute based on matching all functional parameters and package specifications. While the CD4024BE offers enhanced performance characteristics (24 MHz count rate versus 12 MHz, and 3V to 18V supply range), these represent improvements that maintain full backward compatibility with CD4024BCN circuit designs.
