74ACT32MTCX OR Gate IC Equivalent & Substitute Parts

Part Overview

The 74ACT32MTCX is a 4-channel 2-input OR gate logic IC manufactured by onsemi in a 14-TSSOP surface mount package. This component is actively produced and widely used in digital logic applications requiring OR gate functionality. Substitute parts may be required due to supply chain constraints, packaging preferences, or manufacturer availability across different regions.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74ACT32MTCX is determined by strict equivalence across the following parameters: logic type (OR Gate), number of circuits (4), number of inputs (2), supply voltage range (4.5V ~ 5.5V), output current capability (24mA, 24mA), input logic levels (0.8V low, 2V high), propagation delay (9ns @ 5V, 50pF), operating temperature range (-40°C ~ 85°C), and package type (14-TSSOP). All substitute parts must maintain identical functional specifications and package dimensions to ensure direct interchangeability in circuit designs.

Substitute parts are categorized as follows:

Direct Substitutes: Parts with identical electrical and mechanical specifications, differing only in packaging format (Cut Tape vs. Tape & Reel).

Similar Substitutes: Parts with equivalent electrical specifications but different packaging or product status considerations.

Parameter Comparison

Engineering Selection Recommendations

MC74ACT32DTR2G (onsemi): Direct electrical equivalent to the 74ACT32MTCX with identical specifications. The primary difference is packaging format (Tape & Reel vs. Cut Tape). This part is actively produced and ROHS3 compliant. Selection is appropriate for high-volume manufacturing environments where Tape & Reel packaging is standard.

SN74ACT32PWR (Texas Instruments): Direct electrical equivalent with identical functional specifications. Quiescent current is lower at 2 µA compared to 4 µA in the onsemi variants. Packaging format is Cut Tape & Digi-Reel®, matching the main part. This part is actively produced and ROHS3 compliant. Selection is appropriate when Texas Instruments sourcing is preferred or when lower quiescent current is beneficial.

SN74ACT32PW (Texas Instruments): Electrically equivalent to the 74ACT32MTCX with identical functional specifications and lower quiescent current (2 µA). Packaging format is Tube. Product status is discontinued at DiGi Electronics, indicating limited availability. This part should be selected only when existing inventory is available and long-term supply is not a requirement.

Frequently Asked Questions (FAQ)

Q: Can MC74ACT32DTR2G replace 74ACT32MTCX directly in production?

A: Yes. MC74ACT32DTR2G is electrically and mechanically identical to 74ACT32MTCX. The only difference is packaging format (Tape & Reel vs. Cut Tape). Both are 14-TSSOP surface mount packages with identical pin configurations and electrical performance.

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

A: All versions maintain identical logic functionality, supply voltage range, output current, input logic levels, propagation delay, operating temperature, and package type. The Texas Instruments variants (SN74ACT32PWR and SN74ACT32PW) have lower quiescent current at 2 µA versus 4 µA for onsemi parts. This difference is negligible in most applications.

Q: Why is SN74ACT32PW marked as discontinued?

A: SN74ACT32PW is discontinued at DiGi Electronics, indicating it is no longer actively stocked by this distributor. However, the part remains functionally equivalent. Use this part only if existing inventory is available and supply continuity is not critical.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed—74ACT32MTCX, MC74ACT32DTR2G, SN74ACT32PWR, and SN74ACT32PW—are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: What packaging format should I select?

A: Selection depends on manufacturing process. Cut Tape & Digi-Reel® (74ACT32MTCX, SN74ACT32PWR) is suitable for automated pick-and-place equipment. Tape & Reel (MC74ACT32DTR2G) is standard for high-volume production. Tube packaging (SN74ACT32PW) is used for manual assembly or lower-volume applications.

Q: Can these parts be used interchangeably in the same circuit board design?

A: Yes. All substitute parts have identical 14-TSSOP package dimensions (0.173", 4.40mm Width) and pin configurations. PCB layouts and schematics require no modification for substitution.
