DM7486N XOR Logic IC - Equivalent & Substitute Parts

Part Overview

The DM7486N is a 4-channel, 2-input XOR (Exclusive OR) logic integrated circuit manufactured by onsemi in the 7400 series. This component is classified as obsolete, which necessitates identification of active equivalent parts for new designs and ongoing production requirements. The DM7486N operates within a 4.75V to 5.25V supply voltage range and is housed in a 14-MDIP through-hole package. Due to its obsolete status, sourcing active alternatives with identical electrical and mechanical specifications is essential for design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DM7486N is determined by strict equivalence across the following critical parameters:

• Logic Function: XOR gate with 4 channels and 2 inputs per channel
• Electrical Specifications: Supply voltage range (4.75V ~ 5.25V), output current ratings (800µA high, 16mA low), input logic thresholds (0.8V low, 2V high), and propagation delay (30ns @ 5V, 15pF)
• Mechanical Compatibility: Through-hole mounting in 14-DIP package with 0.300" (7.62mm) pitch
• Operating Range: 0°C to 70°C ambient temperature

The SN74LS86ANE4 from Texas Instruments meets all these criteria and is classified as an active product, making it a direct parametric equivalent for the obsolete DM7486N.

Engineering Selection Recommendations

The SN74LS86ANE4 is the direct substitute for the DM7486N based on complete electrical and mechanical parameter equivalence. The primary advantage of selecting the SN74LS86ANE4 is its active product status, ensuring long-term availability and supply chain reliability. Additionally, the SN74LS86ANE4 carries ROHS3 compliance, whereas the DM7486N is RoHS non-compliant. For applications requiring RoHS compliance or operating in regulated environments, the SN74LS86ANE4 is the appropriate selection. Both components are REACH unaffected and classified under ECCN EAR99.

Frequently Asked Questions (FAQ)

Q: Can the SN74LS86ANE4 be used as a direct replacement for the DM7486N in existing designs?

A: Yes. The SN74LS86ANE4 is electrically and mechanically equivalent to the DM7486N across all specified parameters, including supply voltage, output current, input logic levels, propagation delay, operating temperature range, and 14-DIP package configuration. No circuit modifications are required.

Q: What is the primary reason for substituting the DM7486N?

A: The DM7486N is classified as obsolete. The SN74LS86ANE4 is an active product from Texas Instruments, providing assured long-term availability and supply chain continuity.

Q: Are there packaging differences between these parts?

A: Both the DM7486N and SN74LS86ANE4 use 14-DIP through-hole packages with identical 0.300" (7.62mm) pitch. They are mechanically interchangeable on PCBs designed for standard DIP sockets.

Q: Does the SN74LS86ANE4 meet modern compliance requirements?

A: The SN74LS86ANE4 is ROHS3 compliant and REACH unaffected. The DM7486N is RoHS non-compliant. For applications subject to RoHS or environmental regulations, the SN74LS86ANE4 is the appropriate choice.

Q: Are the electrical performance characteristics identical?

A: Yes. Both parts operate at 4.75V to 5.25V supply voltage, deliver identical output current ratings (800µA high, 16mA low), maintain the same input logic thresholds (0.8V low, 2V high), and exhibit 30ns maximum propagation delay at 5V with 15pF load capacitance.
