74HCT04DB,118 Equivalent & Substitute Parts

Part Overview

The 74HCT04DB,118 is a 6-channel inverter logic IC manufactured by Nexperia USA Inc. in a 14-SSOP surface mount package. This part is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement. The 74HCT04 series provides standard CMOS inverter functionality suitable for digital logic applications requiring signal inversion across multiple channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74HCT04DB,118 is determined by the following critical parameters:

• Logic Function: All substitute parts must be 6-channel inverters with single input per channel
• Supply Voltage Range: 4.5V ~ 5.5V compatibility required
• Electrical Characteristics: Quiescent current, output drive current, input logic levels, and propagation delay must meet or exceed the original specification
• Operating Temperature Range: Minimum -40°C support required; extended range (-55°C) is acceptable
• Package Type: Surface mount packages (SSOP, TSSOP) are mechanically compatible with appropriate PCB footprint verification
• Compliance: ROHS3 compliance and MSL Level 1 required

All listed substitute parts share the 74HCT04 base product number and maintain functional equivalence within these parameters.

Engineering Selection Recommendations

Primary Recommendation: SN74HCT04PWR

The SN74HCT04PWR from Texas Instruments is the preferred substitute for the obsolete 74HCT04DB,118. This part maintains active product status, ensuring long-term availability and supply chain stability. It meets all electrical specifications and operating temperature requirements of the original part. The 14-TSSOP package is mechanically compatible with appropriate PCB footprint adjustment. ROHS3 compliance and MSL Level 1 certification align with the original part's environmental standards.

Secondary Recommendation: CD74HCT04PWR

The CD74HCT04PWR offers extended operating temperature range (-55°C ~ 125°C) compared to the original specification, providing additional thermal margin for demanding applications. This part is currently active and maintains full electrical equivalence. The 14-TSSOP package requires PCB footprint verification due to dimensional differences from the original 14-SSOP.

Alternative Options: SN74HCT04PW and SN74HCT04PWT

Both parts are discontinued at DiGi Electronics but remain functionally equivalent. These options are suitable only if existing inventory is available and long-term procurement is not required. Operating temperature range is limited to -40°C ~ 85°C, which may restrict use in extended temperature applications.

Frequently Asked Questions (FAQ)

Q: Can I directly replace the 74HCT04DB,118 with any of these substitute parts?

A: Electrical substitution is direct for all listed parts. However, package differences between 14-SSOP and 14-TSSOP require PCB footprint verification. The 14-TSSOP package is narrower (4.40mm vs 5.30mm width), necessitating layout confirmation before implementation.

Q: What is the difference between the Texas Instruments substitute parts?

A: All Texas Instruments 74HCT04 variants share identical electrical characteristics and logic function. Differences exist only in packaging format (Tape & Reel, Tube, or Cut Tape) and product status. SN74HCT04PWR and CD74HCT04PWR are currently active; SN74HCT04PW and SN74HCT04PWT are discontinued.

Q: Does operating temperature range affect substitution compatibility?

A: The original part specifies -40°C ~ 125°C operation. Substitute parts with identical or extended ranges are fully compatible. SN74HCT04PW and SN74HCT04PWT have reduced upper temperature limit (85°C), which may restrict use in high-temperature environments but remain compatible for standard industrial applications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL Level 1 certification, matching the environmental standards of the original 74HCT04DB,118.

Q: Which substitute part offers the best long-term availability?

A: SN74HCT04PWR is recommended for new designs requiring sustained procurement. This part maintains active status with Texas Instruments and is widely stocked by authorized distributors.
