Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74LS06NG4 is determined by strict equivalence across the following critical parameters:

• Logic type and circuit configuration (6-channel inverter with open collector output)
• Electrical specifications (supply voltage range 4.75V ~ 5.25V, output current 40mA, input logic levels, propagation delay)
• Physical package format (14-DIP through-hole mounting)
• Series classification (74LS logic family)
• Compliance certifications (ROHS3, REACH Unaffected, EAR99)

The SN74LS06N qualifies as a direct substitute based on identical electrical performance, matching package specifications, and equivalent functional characteristics. The primary distinction is packaging format and product status availability.

Parameter Comparison

Engineering Selection Recommendations

The SN74LS06N is the appropriate substitute for the discontinued SN74LS06NG4. Both devices maintain identical electrical specifications, functional characteristics, and physical package dimensions. The SN74LS06N carries active product status with established supply chain availability, addressing the discontinuation of the original part number.

Both parts satisfy ROHS3 compliance and REACH regulatory requirements. Selection between these parts is determined by packaging requirements and inventory availability rather than electrical or functional differences.

Frequently Asked Questions (FAQ)

Q: Are the SN74LS06NG4 and SN74LS06N electrically identical?

A: Yes. Both devices provide identical electrical performance across all specified parameters including supply voltage, output current, input logic levels, and propagation delay characteristics.

Q: What is the difference between these part numbers?

A: The primary difference is product status and packaging format. The SN74LS06NG4 is discontinued, while the SN74LS06N maintains active status. The SN74LS06N is supplied in tube packaging.

Q: Can the SN74LS06N be used as a direct replacement in existing designs?

A: Yes. The SN74LS06N is a direct functional and pin-compatible replacement. The 14-DIP package dimensions are identical, enabling direct substitution in through-hole PCB applications.

Q: Are there any compliance or certification differences?

A: Both parts maintain ROHS3 compliance and REACH Unaffected status. No compliance differences exist between the two part numbers.

Q: What is the operating temperature range for both parts?

A: Both the SN74LS06NG4 and SN74LS06N operate across 0°C to 70°C.
