Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 74ACT16623DL are qualified based on the following critical parameters that determine functional and mechanical compatibility:

• Logic Type: Transceiver, Non-Inverting
• Number of Elements: 2
• 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: 48-BSSOP (0.295", 7.50mm Width)
• Mounting Type: Surface Mount

All substitute parts listed maintain these electrical and mechanical specifications, ensuring direct functional equivalence. Variations in manufacturer, product status, packaging format (Tube vs. Cut Tape vs. Bulk), and compliance certifications are noted but do not affect core circuit compatibility.

Parameter Comparison

Engineering Selection Recommendations

When selecting a substitute for the 74ACT16623DL, prioritize parts with Active product status for new designs and long-term supply assurance. The 74FCT162H245CTPVC (Cypress Semiconductor Corp, Active status, 8365 units in stock) and CY74FCT162245ATPVC (Cypress Semiconductor Corp, Active status, 1217 units in stock) offer the best availability and lifecycle continuity.

For existing designs requiring the original 74ACT16623DL, the 74ACT16245DL (Texas Instruments, Last Time Buy, 3840 units in stock) provides equivalent electrical performance with higher current inventory. Both parts maintain ROHS3 compliance and identical electrical specifications.

Parts with Obsolete status (74ACT16623DLR, 74FCT162245ATPVG, 74FCT162H245ATPVC, CY74FCT162245CTPVC) are suitable for replacement only when inventory depletion is imminent or when design modifications are acceptable. Moisture Sensitivity Level (MSL) varies between 1 (Unlimited) and 3 (168 Hours); verify storage and handling requirements based on your manufacturing environment.

Frequently Asked Questions (FAQ)

Q: Can I use 74ACT16245DL as a direct replacement for 74ACT16623DL?

A: Yes. Both parts share identical electrical specifications (2 elements, 8 bits per element, 3-state output, 24mA output current, 4.5V–5.5V supply, -40°C to 85°C operating range) and the same 48-BSSOP package. The primary difference is the base product number (74ACT16245 vs. 74ACT16623), which does not affect circuit compatibility.

Q: What is the difference between 74FCT and 74ACT series parts?

A: Both series are non-inverting transceiver logic families with identical electrical parameters for this application. The 74FCT series (Fast CMOS Technology) and 74ACT series (Advanced CMOS Technology) maintain the same voltage supply range, output current ratings, and operating temperature specifications. Selection between series is based on product status and availability rather than electrical performance.

Q: Are there packaging differences between substitute parts?

A: All listed substitutes use the 48-BSSOP package. Packaging format variations (Tube, Cut Tape, Bulk) affect handling and storage but not electrical or mechanical compatibility. Verify your procurement and assembly process requirements when selecting between packaging formats.

Q: What does Moisture Sensitivity Level (MSL) 1 vs. MSL 3 mean for my application?

A: MSL 1 (Unlimited) allows indefinite shelf storage without baking. MSL 3 (168 Hours) requires baking if the part has been exposed to moisture for more than 168 hours. Confirm your manufacturing environment's humidity control and storage duration to determine which MSL rating is acceptable.

Q: Why is 74ACT16623DL marked as Last Time Buy?

A: Last Time Buy status indicates the manufacturer will discontinue production. Existing inventory will be sold until depletion, after which the part becomes unavailable. Plan design transitions to Active-status alternatives such as 74FCT162H245CTPVC or CY74FCT162245ATPVC to ensure long-term supply continuity.

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

A: Yes. All listed substitutes maintain identical electrical specifications and package dimensions. Mixing manufacturers (Texas Instruments, Cypress Semiconductor Corp, National Semiconductor, Renesas Electronics Corporation) within the same circuit is electrically compatible. Verify procurement lead times and cost implications when sourcing from multiple manufacturers.
