74ACT00MTCX Equivalent & Substitute Parts

Part Overview

The 74ACT00MTCX is a NAND Gate IC featuring 4 channels with 2 inputs per channel in a 14-TSSOP surface mount package, manufactured by onsemi. This logic component operates within the 4.5V to 5.5V supply voltage range and is designed for general-purpose digital logic applications requiring NAND gate functionality. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating. Equivalent and substitute parts are identified to provide design flexibility, accommodate supply chain variations, and support alternative packaging or operational temperature requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74ACT00MTCX is determined by equivalence in the following critical parameters: logic type (NAND Gate), circuit count (4 channels), input count (2 inputs per channel), supply voltage range (4.5V ~ 5.5V), output current capability (24mA high and low), input logic thresholds (0.8V low, 2V high), and propagation delay (9ns @ 5V, 50pF). All substitute parts maintain the 74ACT base product number and series designation, ensuring functional compatibility at the logic level.

Substitutes are categorized as follows:

Direct Manufacturer Substitutes maintain identical electrical parameters and package specifications, differing only in packaging format (Cut Tape vs. Tape & Reel) or manufacturer source.

Similar Substitutes maintain all electrical parameters but employ a different package variant (14-SSOP vs. 14-TSSOP), requiring PCB layout adjustment.

Parametric Equivalents maintain all electrical parameters and identical packaging, with variations in operating temperature range or quiescent current that do not affect functional compatibility within the specified operating conditions.

Parameter Comparison

Engineering Selection Recommendations

MC74ACT00DTR2G is suitable for applications requiring extended operating temperature range (-55°C to 125°C) while maintaining identical electrical performance and package footprint. This part is currently active in production with full compliance certifications.

SN74ACT00PWR provides direct functional and electrical equivalence with identical package specifications and operating temperature range. This part is currently active in production with full compliance certifications and represents the primary Texas Instruments alternative.

SN74ACT00PW maintains electrical and package equivalence but is discontinued at DiGi Electronics, limiting availability for new designs. Use only when existing inventory is available and supply continuity is not a design requirement.

SN74ACT00DBR maintains all electrical parameters but employs a 14-SSOP package (0.209" width) instead of the 14-TSSOP package (0.173" width). PCB layout modification is required for this substitution. This part is currently active in production with full compliance certifications.

All substitute parts maintain RoHS3 compliance, unlimited moisture sensitivity rating (MSL 1), and REACH unaffected status, ensuring regulatory equivalence with the primary part.

Frequently Asked Questions (FAQ)

Q: Can MC74ACT00DTR2G be used as a direct replacement for 74ACT00MTCX?

A: Yes. MC74ACT00DTR2G maintains identical electrical parameters, supply voltage range, output current capability, input logic thresholds, and propagation delay. The primary difference is extended operating temperature range (-55°C to 125°C vs. -40°C to 85°C) and packaging format (Tape & Reel vs. Cut Tape). Functional compatibility is maintained for applications operating within the -40°C to 85°C range.

Q: What is the difference between 14-TSSOP and 14-SSOP packages?

A: Both are surface mount packages with 14 pins, but differ in body width. The 14-TSSOP is 0.173" (4.40mm) wide, while the 14-SSOP is 0.209" (5.30mm) wide. PCB footprint and land pattern differ between these packages, requiring layout modification when substituting SN74ACT00DBR for the primary part.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain RoHS3 compliance, REACH unaffected status, and unlimited moisture sensitivity rating (MSL 1), ensuring regulatory equivalence with 74ACT00MTCX.

Q: Why is SN74ACT00PW listed as discontinued?

A: SN74ACT00PW is discontinued at DiGi Electronics, indicating limited availability through primary distribution channels. This part should be used only when existing inventory is confirmed available and supply continuity is not a design requirement.

Q: What is the significance of quiescent current differences between parts?

A: MC74ACT00DTR2G specifies 4 µA maximum quiescent current compared to 2 µA for other parts. This difference does not affect functional compatibility but may impact power consumption in applications with extended idle periods or high-volume deployments.

Q: Can these parts be used interchangeably in existing designs?

A: SN74ACT00PWR and SN74ACT00PW are direct pin-for-pin and footprint-compatible replacements. MC74ACT00DTR2G is pin-compatible and footprint-compatible but offers extended temperature range. SN74ACT00DBR requires PCB layout modification due to different package dimensions. All maintain identical logic functionality and electrical performance within specified operating conditions.
