Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DM74153N is determined by the following critical parameters:

• Functional Circuit: 2 x 4:1 multiplexer configuration
• Package Type: 16-DIP (0.300", 7.62mm) through-hole mounting
• Voltage Supply Source: Single supply operation
• Pin Compatibility: Identical pinout and signal routing

The CD74ACT153E qualifies as a substitute based on matching circuit topology (2 x 4:1 multiplexer), identical package format (16-DIP), and compatible single supply voltage operation. Both parts maintain the same functional behavior and physical footprint, enabling direct replacement in PCB designs.

Parameter Comparison

Engineering Selection Recommendations

The CD74ACT153E serves as a direct functional substitute for the DM74153N based on identical circuit topology and package format. Both components are classified as obsolete, reflecting their legacy status in modern component inventories. The CD74ACT153E operates within a broader voltage supply range (4.5V ~ 5.5V versus 4.75V ~ 5.25V) and supports an extended operating temperature range (-55°C ~ 125°C versus 0°C ~ 70°C), providing additional operational flexibility in certain applications. Output current specifications are defined for the CD74ACT153E (24mA, 24mA) but not provided for the DM74153N. Both parts maintain RoHS non-compliant status and identical ECCN and HTSUS classifications.

Frequently Asked Questions (FAQ)

Q: Can the CD74ACT153E replace the DM74153N in existing designs?

A: Yes. Both components feature identical 2 x 4:1 multiplexer circuit topology and 16-DIP package format, enabling direct PCB substitution without layout modifications.

Q: What are the key differences between these parts?

A: The primary differences are manufacturer origin (onsemi versus Harris Corporation), series designation (7400 versus 74ACT), and operational specifications. The CD74ACT153E provides defined output current ratings (24mA, 24mA) and operates across a wider voltage range and temperature range.

Q: Are there voltage compatibility concerns?

A: The DM74153N operates at 4.75V ~ 5.25V, while the CD74ACT153E operates at 4.5V ~ 5.5V. The CD74ACT153E's broader range encompasses the DM74153N specification, ensuring compatibility in standard 5V supply applications.

Q: What is the significance of the obsolete product status?

A: Both components are obsolete, indicating discontinued manufacturing. Existing inventory may be available through authorized distributors, but long-term sourcing should consider alternative modern multiplexer solutions for new designs.

Q: Does package format affect substitution?

A: No. Both parts use identical 16-DIP (0.300", 7.62mm) through-hole packaging, ensuring mechanical and electrical compatibility without PCB redesign.
