CD74HC4059E Equivalent & Substitute Parts

Part Overview

The CD74HC4059E is a 16-bit divide-by-N counter IC manufactured by Texas Instruments, housed in a 24-DIP through-hole package. This logic component functions as a programmable counter with asynchronous reset and synchronous timing, operating at a maximum count rate of 32 MHz across a supply voltage range of 2V to 6V.

The CD74HC4059E is classified as obsolete. Locating equivalent substitute parts is necessary for new designs, production continuity, and system upgrades where through-hole components may no longer be preferred or available in sufficient quantities.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD74HC4059E is determined by functional equivalence across the following critical parameters:

• Logic Type: Divide-by-N counter function
• Bit Width: 16-bit configuration
• Count Rate: 32 MHz maximum frequency
• Trigger Mechanism: Positive edge triggering
• Reset Architecture: Asynchronous reset capability
• Timing Mode: Synchronous operation
• Supply Voltage Range: 2V to 6V compatibility
• Temperature Range: -55°C to 125°C operation

The CD74HC4059M96 maintains identical functional specifications and electrical characteristics. The primary difference is packaging format: the substitute transitions from through-hole (24-DIP) to surface-mount (24-SOIC) technology, with corresponding changes to mounting type and physical dimensions.

Parameter Comparison

Engineering Selection Recommendations

The CD74HC4059M96 is the direct functional equivalent of the CD74HC4059E. Both components are manufactured by Texas Instruments and share identical electrical specifications, logic functionality, and performance characteristics.

The CD74HC4059M96 holds active product status, ensuring ongoing availability and manufacturing support. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements.

The primary consideration for component selection is packaging format. The CD74HC4059E uses through-hole mounting (24-DIP), while the CD74HC4059M96 uses surface-mount technology (24-SOIC). This difference affects PCB layout, assembly process, and board real estate. Through-hole components require mechanical insertion and wave soldering or manual soldering, whereas surface-mount components integrate with automated pick-and-place assembly and reflow soldering processes.

Frequently Asked Questions (FAQ)

Q: Can the CD74HC4059M96 directly replace the CD74HC4059E in existing designs?

A: Electrical and functional replacement is complete. Pin-to-pin compatibility exists at the signal level. However, physical package differences (24-DIP versus 24-SOIC) require PCB redesign. Through-hole footprints cannot accommodate surface-mount components without layout modification.

Q: What are the key differences between these two parts?

A: The CD74HC4059E and CD74HC4059M96 are electrically and functionally identical. Differences are limited to packaging format, mounting technology, and physical dimensions. The CD74HC4059E is obsolete; the CD74HC4059M96 is active production.

Q: Are there any performance differences between through-hole and surface-mount versions?

A: No. Both versions operate at identical specifications: 32 MHz count rate, 2V to 6V supply voltage, -55°C to 125°C temperature range, and all functional parameters remain unchanged.

Q: What compliance certifications apply to both parts?

A: Both the CD74HC4059E and CD74HC4059M96 are ROHS3 compliant and REACH unaffected. Moisture sensitivity level is 1 (unlimited) for both versions.

Q: Which part should be selected for new designs?

A: The CD74HC4059M96 is recommended for new designs due to active product status and alignment with modern surface-mount assembly practices. The CD74HC4059E should be reserved for legacy system maintenance only.
