74ACT08MTCX Equivalent & Substitute Parts

Part Overview

The 74ACT08MTCX is a 4-channel 2-input AND gate logic IC manufactured by onsemi in a 14-TSSOP surface mount package. This component is classified as an active product and is currently in stock with 23,609 units available. The 74ACT08 series represents a standard logic gate function widely used in digital circuit design. Substitute parts are necessary when the primary part becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when sourcing from multiple suppliers is needed for supply chain resilience.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74ACT08MTCX is determined by the following critical parameters that must remain constant across all equivalent parts:

• Logic function: 4-channel 2-input AND gate
• Electrical specifications: 4.5V ~ 5.5V supply voltage, -40°C ~ 85°C operating temperature range
• Package type: 14-TSSOP surface mount package with identical pinout and mechanical dimensions
• Compliance: ROHS3 compliance and MSL Level 1 rating

Substitute parts are grouped into two categories:

Direct Substitutes (Identical Specifications): Parts that maintain all electrical parameters and differ only in packaging format (Cut Tape vs. Tape & Reel).

Similar Substitutes (Minor Parameter Variance): Parts that maintain functional equivalence and core electrical specifications but may differ in quiescent current specifications or product status.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (74ACT08MTCX): This part is the recommended choice for new designs and applications requiring immediate availability. It maintains active product status with the highest inventory level and is supplied in Cut Tape format suitable for automated pick-and-place assembly operations.

Direct Substitute (MC74ACT08DTR2G): This onsemi equivalent is functionally identical to the primary part with identical electrical specifications. The difference lies in packaging format (Tape & Reel vs. Cut Tape). This substitute is suitable when Tape & Reel packaging is required for high-volume manufacturing processes. Both parts are manufactured by onsemi and maintain identical quiescent current specifications.

Alternative Substitute (SN74ACT08PWR): This Texas Instruments equivalent maintains all critical functional parameters and is suitable for applications where multi-source qualification is required. The quiescent current specification is lower (2 µA vs. 4 µA), which represents an improvement in power efficiency. This part is supplied in Tape & Reel format and is currently in active production status.

Secondary Substitute (SN74ACT08PW): This Texas Instruments part is functionally equivalent but is discontinued at DiGi Electronics. It is supplied in Tube packaging format. This part should be selected only when existing inventory is available and Tube packaging is compatible with assembly processes. The lower quiescent current specification (2 µA) matches the SN74ACT08PWR variant.

All substitute parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with standard manufacturing and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can I use MC74ACT08DTR2G as a direct replacement for 74ACT08MTCX?

A: Yes. Both parts are manufactured by onsemi and maintain identical electrical specifications, operating temperature range, supply voltage, and logic function. The only difference is packaging format: 74ACT08MTCX is supplied in Cut Tape format while MC74ACT08DTR2G is supplied in Tape & Reel format. The 14-TSSOP package dimensions and pinout are identical.

Q: What is the difference between the onsemi and Texas Instruments versions?

A: Both manufacturers produce functionally equivalent 74ACT08 AND gate ICs in the same 14-TSSOP package with identical pinouts and core electrical specifications. The onsemi versions (74ACT08MTCX and MC74ACT08DTR2G) specify a maximum quiescent current of 4 µA, while the Texas Instruments versions (SN74ACT08PWR and SN74ACT08PW) specify 2 µA. All other electrical parameters, including output current, propagation delay, and logic thresholds, are identical.

Q: Is SN74ACT08PW still available for new designs?

A: SN74ACT08PW is discontinued at DiGi Electronics and should not be selected for new designs. Use SN74ACT08PWR (Tape & Reel) or 74ACT08MTCX (Cut Tape) for active product availability.

Q: What packaging formats are available?

A: Three packaging formats are available: Cut Tape (74ACT08MTCX), Tape & Reel (MC74ACT08DTR2G and SN74ACT08PWR), and Tube (SN74ACT08PW). Cut Tape and Tape & Reel formats are suitable for automated assembly. Tube packaging is used for manual assembly or lower-volume applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed parts maintain ROHS3 compliance and MSL Level 1 rating, meeting standard environmental and manufacturing requirements.

Q: Can I mix different manufacturers in the same design?

A: Yes. All parts maintain identical pinouts, package dimensions, and core electrical specifications. However, the quiescent current specification differs between manufacturers (onsemi: 4 µA maximum; Texas Instruments: 2 µA maximum). This difference should be considered in power budget calculations for applications with strict power consumption requirements.
