74AC00MTC NAND Gate IC Equivalent & Substitute Parts

Part Overview

The 74AC00MTC is a 4-channel 2-input NAND gate logic IC manufactured by onsemi in a 14-TSSOP surface mount package. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The 74AC00 series represents a standard logic function across multiple manufacturers, enabling direct functional substitution based on electrical and mechanical parameter alignment.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74AC00MTC is determined by strict alignment of the following parameters:

• Logic Function: All substitutes must implement 4-channel 2-input NAND gate logic
• Package: All substitutes must use 14-TSSOP surface mount package with identical pinout
• Voltage Supply: All substitutes must support 2V ~ 6V operating range
• Output Drive Capability: All substitutes must provide 24mA output current (high and low)
• Propagation Delay: All substitutes must meet 8ns maximum delay specification at 5V, 50pF load
• Input Logic Levels: All substitutes must accept 0.9V ~ 1.65V (low) and 2.1V ~ 3.85V (high) input thresholds
• Compliance: All substitutes must maintain ROHS3 compliance and REACH unaffected status

Substitutes are grouped into two categories based on product status and availability:

Direct Manufacturer Substitutes (Active Status): MC74AC00DTR2G (onsemi), SN74AC00PWR (Texas Instruments)

Parametric Equivalent (Discontinued Status): SN74AC00PW (Texas Instruments)

Parameter Comparison

Engineering Selection Recommendations

MC74AC00DTR2G (onsemi) is the primary substitute for the 74AC00MTC. Both parts are manufactured by onsemi and maintain identical electrical specifications. The MC74AC00DTR2G offers extended operating temperature range (-55°C ~ 125°C) compared to the main part (-40°C ~ 85°C), providing broader environmental compatibility. This part carries active product status with high inventory availability (20,300 pcs), ensuring reliable procurement. Packaging is supplied as Cut Tape and Digi-Reel, suitable for automated assembly processes.

SN74AC00PWR (Texas Instruments) serves as an alternative direct manufacturer substitute. This part maintains identical electrical and thermal specifications to the 74AC00MTC (-40°C ~ 85°C operating range, 2 µA quiescent current). The SN74AC00PWR is supplied in Tape & Reel packaging with active product status and substantial inventory (30,400 pcs). Selection of this part introduces Texas Instruments as the manufacturer while preserving all functional and compliance requirements.

SN74AC00PW (Texas Instruments) is classified as a parametric equivalent with discontinued status at DiGi Electronics. This part maintains electrical equivalence to the main part but carries reduced inventory (1,252 pcs) and discontinued product status. Selection of this part should be limited to applications where existing stock is available and long-term procurement is not required.

All three substitutes maintain ROHS3 compliance, REACH unaffected status, and identical moisture sensitivity levels, ensuring regulatory and environmental compatibility with the original 74AC00MTC specification.

Frequently Asked Questions (FAQ)

Q: Can MC74AC00DTR2G replace 74AC00MTC in all applications?

A: Yes. MC74AC00DTR2G meets all electrical specifications of 74AC00MTC and uses the identical 14-TSSOP package. The extended operating temperature range (-55°C ~ 125°C) of MC74AC00DTR2G provides additional environmental margin. Both parts are ROHS3 compliant and REACH unaffected.

Q: What is the difference between the packaging options?

A: 74AC00MTC is supplied in Tube packaging. MC74AC00DTR2G is supplied in Cut Tape and Digi-Reel. SN74AC00PWR is supplied in Tape & Reel. SN74AC00PW is supplied in Tube. All packaging options contain identical die and electrical performance. Packaging selection depends on assembly process requirements and order quantity.

Q: Are there differences in quiescent current between substitutes?

A: MC74AC00DTR2G specifies 4 µA maximum quiescent current, while 74AC00MTC, SN74AC00PWR, and SN74AC00PW specify 2 µA. This difference is within normal manufacturing variation for the 74AC series and does not affect functional compatibility. Applications with strict power consumption requirements should account for this specification variance.

Q: Why is SN74AC00PW listed as discontinued?

A: SN74AC00PW is discontinued at DiGi Electronics but remains a parametric equivalent to 74AC00MTC. This part should be selected only when existing inventory is available. For new designs and ongoing procurement, MC74AC00DTR2G or SN74AC00PWR are recommended due to active product status.

Q: Do all substitutes support the same voltage supply range?

A: Yes. All substitutes support 2V ~ 6V supply voltage range, matching the 74AC00MTC specification. Input logic levels and output drive capability are identical across all parts.

Q: Is the 14-TSSOP package pinout identical across all substitutes?

A: Yes. All substitutes use the 14-TSSOP package with 0.173" width and 4.40mm body dimension. Pinout is identical, enabling direct PCB footprint compatibility without layout modification.
