74ACT16652DLR Equivalent & Substitute Parts

Part Overview

The 74ACT16652DLR is a non-inverting transceiver logic integrated circuit manufactured by Texas Instruments. This device functions as a 2-element, 8-bit per element transceiver with 3-state output capability, designed for 5.5V operation in surface mount 56-SSOP packaging. The part is currently active in production status with ROHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are necessary when the primary part number becomes unavailable due to inventory constraints, supply chain disruptions, or when design flexibility permits selection from functionally equivalent alternatives within the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 74ACT16652DLR are qualified based on strict electrical and mechanical parameter matching. All substitute candidates must satisfy the following criteria:

Electrical Equivalence Requirements:

• 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)

Mechanical Equivalence Requirements:

• Mounting Type: Surface Mount
• Package / Case: 56-BSSOP (0.295", 7.50mm Width)
• Supplier Device Package: 56-SSOP

Compliance Requirements:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

All substitute parts listed below meet these criteria. Parts designated as Obsolete status are included for reference in legacy system support scenarios but should not be selected for new designs.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status):

The 74ACT16543DLR, 74ACT16646DLR, and 74ACT16657DLR are recommended as primary substitutes for new designs and production applications. All three parts maintain Active product status with Texas Instruments, ensuring long-term availability and continued manufacturing support. These parts are manufactured within the 74ACT series, providing consistent electrical performance and thermal characteristics. All primary substitutes carry ROHS3 compliance and REACH Unaffected certification, meeting current environmental and regulatory requirements.

Secondary Substitutes (Obsolete Status):

The 74FCT162652ATPVCT and CY74FCT162543TPVCT are designated as Obsolete by the manufacturer. These parts are suitable only for legacy system maintenance, repair, and field replacement scenarios where the original part number is no longer available. Obsolete parts should not be selected for new product designs or production applications due to discontinued manufacturing status and potential future supply unavailability.

Selection Criteria:

Component selection should prioritize Active status parts to ensure design longevity and supply chain stability. All listed substitutes meet identical electrical specifications and mechanical packaging requirements, permitting direct pin-for-pin replacement within the specified operating parameters. Inventory availability should be considered as a secondary factor when multiple Active alternatives exist.

Frequently Asked Questions (FAQ)

Q: Can the 74ACT16543DLR be used as a direct replacement for the 74ACT16652DLR?

A: Yes. The 74ACT16543DLR meets all electrical and mechanical specifications required for direct substitution. Both parts are non-inverting transceivers with 2 elements, 8 bits per element, 3-state output, identical current ratings, supply voltage range, operating temperature range, and 56-BSSOP packaging. Both maintain Active product status and ROHS3 compliance.

Q: What is the difference between Active and Obsolete status parts?

A: Active status indicates the part is currently manufactured and supported by Texas Instruments with ongoing availability. Obsolete status indicates manufacturing has been discontinued. Active parts are suitable for new designs; Obsolete parts are restricted to legacy system support only.

Q: Are the 74FCT series parts compatible with the 74ACT16652DLR?

A: The 74FCT162652ATPVCT and CY74FCT162543TPVCT meet all electrical and mechanical specifications for compatibility. However, both are designated Obsolete and should be used only for legacy system maintenance. For new applications, Active 74ACT series alternatives are recommended.

Q: Does packaging differ between substitute parts?

A: All substitute parts use identical 56-BSSOP (0.295", 7.50mm Width) surface mount packaging with 56-SSOP supplier device package designation. No package conversion or board layout modification is required for substitution.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant certification and REACH Unaffected status, meeting current environmental and regulatory requirements identical to the 74ACT16652DLR.

Q: What is the moisture sensitivity level for substitute parts?

A: All substitute parts maintain Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no moisture sensitivity restrictions during storage, handling, or assembly processes.

Q: Can I use the 74ACT16646DLR in place of the 74ACT16652DLR without circuit modification?

A: Yes. The 74ACT16646DLR is electrically and mechanically equivalent to the 74ACT16652DLR. Pin-for-pin replacement is supported without circuit modification, provided the application operates within the specified voltage and temperature ranges.
