CD4059AM96 Equivalent & Substitute Parts

Part Overview

The CD4059AM96 is a 16-bit divide-by-N counter IC manufactured by Texas Instruments, part of the 4000 series logic family. This component functions as a programmable frequency divider with asynchronous reset capability, operating across a wide supply voltage range of 3V to 12V and supporting count rates up to 12 MHz. The CD4059AM96 is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and production continuity. The primary substitute maintains identical electrical and mechanical specifications while offering active product status and improved availability.

Substitute Part Grouping Explanation

Substitution of the CD4059AM96 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part CD4059AM maintains identical specifications in the following key areas:

Logic function: Divide-by-N counter with 16-bit resolution
Electrical performance: 12 MHz count rate, 3V to 12V supply range, -55°C to 125°C operating temperature
Signal characteristics: Positive edge trigger, asynchronous reset
Physical form factor: 24-SOIC surface mount package with identical dimensions
Regulatory compliance: ROHS3 compliant, REACH unaffected status

The primary distinction between the main part and substitute is product status and packaging format. The CD4059AM is classified as active, ensuring long-term availability and manufacturing support, whereas the CD4059AM96 is obsolete. Both parts share the same base product number (CD4059) and are manufactured by Texas Instruments.
