Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74ACT11623DWR is determined by strict parametric matching across the following critical criteria:

Mandatory Matching Parameters:

• Logic Type: Transceiver, Non-Inverting
• Number of Elements: 1
• Number of Bits per Element: 8
• Output Type: 3-State
• Current - Output High, Low: 24mA, 24mA
• Voltage - Supply: 4.5V ~ 5.5V
• Operating Temperature: -40°C ~ 85°C (TA)
• Package / Case: 24-SOIC (0.295", 7.50mm Width)
• Mounting Type: Surface Mount

All identified substitute parts meet these electrical and mechanical parameters without exception. Variations in product status (active versus obsolete) and moisture sensitivity level do not affect functional equivalence within the specified operating conditions.

Parameter Comparison

Engineering Selection Recommendations

74ACT11245DWR is the primary substitute for the 74ACT11623DWR. This Texas Instruments part maintains identical electrical specifications and package configuration while offering active product status, ensuring continued availability and manufacturing support. The MSL rating of 1 (Unlimited) matches the original component, providing equivalent moisture handling characteristics.

MC74ACT646DWR2G and MC74ACT652DWR2G are functionally equivalent alternatives manufactured by onsemi. Both parts satisfy all mandatory electrical and mechanical parameters. These components carry MSL rating 3 (168 Hours), which differs from the original but remains within acceptable moisture sensitivity classifications for standard handling and storage conditions. Both parts are classified as obsolete.

All four parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with current environmental standards.

Frequently Asked Questions (FAQ)

Q: Can 74ACT11245DWR directly replace 74ACT11623DWR in existing designs?

A: Yes. The 74ACT11245DWR provides direct functional equivalence across all critical electrical parameters: 8-bit non-inverting transceiver operation, 24mA output current capability, 4.5V to 5.5V supply voltage range, -40°C to 85°C operating temperature, and 24-SOIC surface mount packaging. No circuit modifications are required.

Q: What is the significance of the MSL rating difference between 74ACT11623DWR and the onsemi substitutes?

A: The original part carries MSL 1 (Unlimited), while MC74ACT646DWR2G and MC74ACT652DWR2G carry MSL 3 (168 Hours). MSL 3 indicates the component must be used within 168 hours of moisture exposure during storage. For standard manufacturing and assembly environments with proper moisture control, this difference does not impact functional performance or reliability.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All substitute parts are housed in 24-SOIC (0.295", 7.50mm Width) surface mount packages with identical pin configurations and mechanical dimensions, enabling direct PCB layout compatibility.

Q: Why is 74ACT11245DWR recommended over the onsemi alternatives?

A: The 74ACT11245DWR maintains active product status from Texas Instruments, ensuring ongoing manufacturing availability and supply chain stability. The MSL rating of 1 (Unlimited) also matches the original component specification. The onsemi parts, while functionally equivalent, are classified as obsolete.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All four parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.
