74AC00MTCX NAND Gate IC Equivalent & Substitute Parts

Part Overview

The 74AC00MTCX is a 4-channel 2-input NAND gate logic IC manufactured by onsemi in a 14-TSSOP surface mount package. This component is part of the 74AC logic family and is currently in active production status. The 74AC00MTCX serves as a fundamental building block in digital logic circuits requiring NAND gate functionality with AC-series speed and power characteristics. Equivalent and substitute parts are identified based on matching electrical specifications, package compatibility, and functional equivalence within the 74AC logic family.

Substitute Part Grouping Explanation

Substitute parts for the 74AC00MTCX are classified based on functional and electrical equivalence within the 74AC NAND gate family. The substitution criteria are determined by the following key parameters:

Logic function: 4-channel 2-input NAND gate
Package type: 14-TSSOP surface mount
Voltage supply range: 2V to 6V
Output drive capability: 24mA high and low
Propagation delay: 8ns @ 5V, 50pF
RoHS3 compliance and MSL Level 1 rating

Parts are grouped into two categories: direct manufacturer equivalents from onsemi and parametric equivalents from Texas Instruments. All substitute parts maintain identical logic function, package footprint, and core electrical performance specifications.

Engineering Selection Recommendations

Primary Substitute: SN74AC00PWR

The SN74AC00PWR from Texas Instruments is the recommended parametric equivalent for the 74AC00MTCX. Both parts share identical electrical specifications, operating temperature range, quiescent current ratings, and output drive characteristics. The SN74AC00PWR maintains active product status and is available in Tape & Reel packaging, matching the original part's supply format. Both parts are ROHS3 compliant with MSL Level 1 rating.

Secondary Substitute: MC74AC00DTR2G

The MC74AC00DTR2G from onsemi is a direct manufacturer equivalent with extended operating temperature range (-55°C to 125°C) and slightly elevated quiescent current (4 µA maximum). This part is suitable for applications requiring wider temperature operation. The MC74AC00DTR2G is available in higher inventory quantities and is supplied in Cut Tape & Digi-Reel® packaging.

Alternative Substitute: SN74AC00PW

The SN74AC00PW from Texas Instruments matches the electrical specifications of the 74AC00MTCX but carries a discontinued status at DiGi Electronics. This part should be considered only when other substitutes are unavailable, as long-term supply cannot be assured.

Frequently Asked Questions (FAQ)

Q: Can the MC74AC00DTR2G replace the 74AC00MTCX in all applications?

A: The MC74AC00DTR2G is functionally equivalent with identical logic performance and output drive capability. The primary difference is elevated quiescent current (4 µA vs. 2 µA) and extended operating temperature range (-55°C to 125°C vs. -40°C to 85°C). For applications within the -40°C to 85°C range with standard power consumption requirements, both parts are interchangeable. Applications requiring minimum quiescent current should use the 74AC00MTCX or SN74AC00PWR.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, suitable for high-volume automated assembly. Cut Tape (CT) & Digi-Reel® packaging provides components on tape segments, typically used for lower-volume orders or mixed component requirements. Both packaging formats contain identical components; the difference is in supply format and handling.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The 74AC00MTCX, MC74AC00DTR2G, SN74AC00PW, and SN74AC00PWR are all ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating.

Q: Why is the SN74AC00PW listed as discontinued?

A: The SN74AC00PW is discontinued at DiGi Electronics but may remain available through other distribution channels. The SN74AC00PWR is the active production equivalent from Texas Instruments and is the preferred substitute.

Q: Can I use these parts interchangeably in PCB designs?

A: Yes. All substitute parts use the identical 14-TSSOP package footprint (0.173", 4.40mm width) and are pin-compatible. PCB layouts designed for the 74AC00MTCX accommodate all listed substitute parts without modification.
