DM74S00N NAND Gate IC Equivalent & Substitute Parts

Part Overview

The DM74S00N is a 4-channel 2-input NAND gate logic IC manufactured by onsemi in a 14-MDIP package. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and production continuity. The DM74S00N operates within the 74S logic family standard, which defines its electrical characteristics and pin configuration. Identifying compatible substitutes requires matching core electrical parameters, logic function, package type, and pin compatibility.

Substitute Part Grouping Explanation

Substitution of the DM74S00N is determined by strict equivalence across the following criteria:

• Logic Function: NAND gate with 4 channels and 2 inputs per channel
• Electrical Specifications: Supply voltage range 4.75V ~ 5.25V, output current ratings 1mA high / 20mA low, input logic thresholds 0.8V low / 2V high
• Timing Performance: Maximum propagation delay of 8ns at 5V with 50pF load
• Operating Temperature Range: 0°C ~ 70°C
• Package Compatibility: 14-DIP through-hole package with 0.300" (7.62mm) pitch
• Base Product Series: 74S logic family standard

The SN74S00N from Texas Instruments meets all these criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The SN74S00N from Texas Instruments is the qualified substitute for the obsolete DM74S00N. Both components share identical logic function, electrical specifications, and package configuration. The SN74S00N offers superior propagation delay performance (5ns versus 8ns), which provides additional timing margin in applications. The SN74S00N maintains active product status with current manufacturing support, ensuring supply chain continuity. The SN74S00N is RoHS3 compliant, meeting modern environmental and regulatory requirements. Pin-to-pin compatibility and functional equivalence are confirmed across all specified parameters.

Frequently Asked Questions (FAQ)

Q: Can the SN74S00N be used as a direct replacement for the DM74S00N?

A: Yes. Both components are pin-to-pin compatible 14-DIP packages with identical logic function, electrical specifications, and operating characteristics. The SN74S00N meets or exceeds all performance parameters of the DM74S00N.

Q: What is the difference in propagation delay between these parts?

A: The DM74S00N specifies a maximum propagation delay of 8ns at 5V with 50pF load. The SN74S00N specifies 5ns under the same conditions. This 3ns improvement provides additional timing margin and does not create compatibility issues in applications designed for the DM74S00N.

Q: Are there package differences between the DM74S00N and SN74S00N?

A: Both components use the 14-DIP (0.300", 7.62mm) through-hole package. Physical dimensions and pin spacing are identical, ensuring direct board-level compatibility.

Q: Why is the DM74S00N listed as obsolete?

A: The DM74S00N has reached end-of-life status with onsemi. The SN74S00N from Texas Instruments remains in active production and is the recommended substitute for new designs and ongoing production requirements.

Q: What compliance certifications apply to the SN74S00N?

A: The SN74S00N is RoHS3 compliant and REACH unaffected. Both the original DM74S00N and substitute SN74S00N share ECCN EAR99 and HTSUS 8542.39.0001 classifications.
