74AC10MTC NAND Gate IC Equivalent & Substitute Parts

Part Overview

The 74AC10MTC is a NAND Gate IC featuring 3 channels with 3 inputs per channel in a 14-TSSOP surface mount package, manufactured by onsemi. This logic component operates across a 2V to 6V supply voltage range and is classified as obsolete. Due to its obsolete status, identifying functionally equivalent and mechanically compatible substitute parts is essential for design continuity and procurement flexibility.

Substitute Part Grouping Explanation

Substitute parts for the 74AC10MTC are classified based on electrical and mechanical compatibility within the 74AC logic series. All substitute candidates maintain identical logic functionality (3-channel NAND gate with 3 inputs), electrical performance parameters (voltage supply, propagation delay, output current), and thermal operating range. Substitution eligibility is determined by:

Matching logic type, circuit count, and input configuration
Identical electrical specifications (supply voltage, quiescent current, output drive capability, propagation delay)
Compatible operating temperature range
Surface mount technology with equivalent or compatible package footprints

The following substitute parts are grouped by package type and product status:

Direct Substitutes (14-TSSOP Package):

Engineering Selection Recommendations

SN74AC10PWR (Texas Instruments) is the primary recommended substitute. This part maintains identical electrical specifications and package footprint (14-TSSOP) to the 74AC10MTC, with the advantage of active product status and ROHS3 compliance. Availability is confirmed at 2464 pieces in stock with Tape & Reel packaging suitable for automated assembly.

SN74AC10DBR (Texas Instruments) is a functionally equivalent alternative with active product status and ROHS3 compliance. The package differs (14-SSOP vs. 14-TSSOP), resulting in a larger footprint (0.209" vs. 0.173" width). This substitute is appropriate for designs where PCB layout can accommodate the larger package or where existing inventory of 14-SSOP footprints is preferred. Stock availability is 10100 pieces.

SN74AC10PW (Texas Instruments) maintains identical electrical specifications and 14-TSSOP package compatibility but carries discontinued status at DiGi Electronics. This part is suitable only for applications where long-term supply assurance is not critical or where existing inventory is available.

Frequently Asked Questions (FAQ)

Q: Can SN74AC10PWR be used as a direct replacement for 74AC10MTC without PCB modifications?

A: Yes. SN74AC10PWR shares identical electrical specifications and the same 14-TSSOP package footprint (0.173", 4.40mm width) as the 74AC10MTC. No PCB layout changes are required for pin-to-pin substitution.

Q: What is the difference between SN74AC10PWR and SN74AC10DBR?

A: Both parts are functionally equivalent with identical electrical performance. The primary difference is package type: SN74AC10PWR uses 14-TSSOP (0.173" width), while SN74AC10DBR uses 14-SSOP (0.209" width). The larger SSOP package may require PCB footprint adjustment. Both are active products with ROHS3 compliance.

Q: Why is the 74AC10MTC listed as obsolete?

A: The 74AC10MTC is manufactured by onsemi and carries obsolete status. Texas Instruments continues to produce functionally equivalent alternatives (SN74AC10PWR and SN74AC10DBR) in active production, ensuring design continuity.

Q: Are all substitute parts ROHS3 compliant?

A: SN74AC10PWR, SN74AC10PW, and SN74AC10DBR are all ROHS3 compliant. The original 74AC10MTC RoHS status is not specified in available documentation.

Q: What packaging options are available for the substitute parts?

A: SN74AC10PWR is supplied in Tape & Reel (TR) packaging for automated assembly. SN74AC10PW is supplied in Tube packaging. SN74AC10DBR is supplied in Tape & Reel (TR) packaging. Selection depends on assembly process requirements and order quantities.

Q: Can SN74AC10PW be used in new designs?

A: SN74AC10PW is discontinued at DiGi Electronics and should not be selected for new designs requiring long-term supply assurance. SN74AC10PWR or SN74AC10DBR are recommended for new applications.
