SN74HC05NG4 Equivalent & Substitute Parts

Part Overview

The SN74HC05NG4 is a 6-channel inverter IC with open drain output configuration, manufactured by Texas Instruments in the 74HC logic series. This component is designed for digital logic applications requiring signal inversion with open drain characteristics, operating across a 2V to 6V supply voltage range. The SN74HC05NG4 is currently discontinued at DiGi Electronics, making substitute parts necessary for ongoing production and maintenance applications. The availability of active equivalent parts ensures design continuity and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74HC05NG4 is based on strict equivalence across the following critical parameters:

• Logic Type: Inverter configuration with 6 channels and single input per channel
• Output Configuration: Open drain topology
• Electrical Specifications: Supply voltage range (2V ~ 6V), quiescent current (2 µA max), output current (5.2mA), input logic levels, and propagation delay (20ns @ 6V, 50pF)
• Package Type: 14-DIP through-hole mounting with identical physical dimensions
• Base Product Number: 74HC05 series designation
• Compliance: ROHS3 compliance and REACH unaffected status

The SN74HC05N qualifies as a direct substitute based on identical electrical and mechanical specifications. The primary distinction is product status and packaging format, with the SN74HC05N currently active in production.

Parameter Comparison

Engineering Selection Recommendations

The SN74HC05N is the appropriate substitute for the discontinued SN74HC05NG4. Both components are manufactured by Texas Instruments and maintain identical electrical and mechanical specifications across all critical parameters. The SN74HC05N carries active product status, ensuring ongoing availability and supply chain continuity. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current manufacturing standards. The through-hole 14-DIP package format is identical, permitting direct board-level substitution without design modification. Selection of the SN74HC05N eliminates obsolescence risk while preserving full functional and electrical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the SN74HC05N be used as a direct replacement for the SN74HC05NG4 in existing designs?

A: Yes. The SN74HC05N is electrically and mechanically identical to the SN74HC05NG4 across all specified parameters, including logic type, channel count, open drain configuration, supply voltage range, current ratings, input logic levels, propagation delay, operating temperature range, and 14-DIP package dimensions. Direct substitution is supported without circuit modification.

Q: What is the primary reason for substituting the SN74HC05NG4?

A: The SN74HC05NG4 is discontinued at DiGi Electronics. The SN74HC05N provides equivalent functionality with active product status, ensuring reliable supply availability for production and maintenance applications.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the SN74HC05NG4 and SN74HC05N maintain ROHS3 compliance and REACH unaffected status. Regulatory requirements are satisfied by either component.

Q: Does the packaging format differ between these parts?

A: The SN74HC05NG4 is supplied in standard packaging, while the SN74HC05N is supplied in tube packaging. Both use identical 14-DIP through-hole package geometry with 0.300" (7.62mm) spacing, permitting direct board-level substitution.

Q: Are the electrical specifications identical?

A: Yes. Supply voltage (2V ~ 6V), quiescent current (2 µA max), output current (5.2mA), input logic levels, propagation delay (20ns @ 6V, 50pF), and operating temperature range (-40°C ~ 85°C) are identical between both parts.
