Substitute Part Grouping Explanation

Substitution eligibility for the 74ACT16652DLRG4 is determined by strict equivalence across the following critical parameters:

• 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: 56-BSSOP (0.295", 7.50mm Width)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All identified substitute parts meet these electrical and mechanical specifications. Substitutes are grouped into two categories: Active product status parts (74ACT16543DLR, 74ACT16646DLR, 74ACT16657DLR) and Obsolete status parts (74FCT162652ATPVCT, CY74FCT162543TPVCT).

Parameter Comparison

Engineering Selection Recommendations

For applications requiring the 74ACT16652DLRG4, the following substitution strategy is recommended based on product status and compliance:

Primary Substitutes (Active Status): 74ACT16543DLR, 74ACT16646DLR, and 74ACT16657DLR are all active products from Texas Instruments within the 74ACT series. These parts maintain full electrical and mechanical equivalence with the discontinued 74ACT16652DLRG4 and are recommended for new designs and ongoing production requirements. All three are ROHS3 compliant with MSL 1 rating.

Secondary Substitutes (Obsolete Status): 74FCT162652ATPVCT and CY74FCT162543TPVCT are obsolete products from the 74FCT series. While electrically and mechanically equivalent, these parts are no longer in active production. Selection of these substitutes should be limited to legacy system maintenance where supply chain continuity is established.

Packaging Consideration: All substitute parts are supplied in 56-SSOP packaging with identical mechanical dimensions (56-BSSOP, 0.295", 7.50mm Width), ensuring direct PCB compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can 74ACT16543DLR, 74ACT16646DLR, and 74ACT16657DLR be used interchangeably with 74ACT16652DLRG4?

A: Yes. These parts are parametric equivalents meeting all electrical specifications (2-element, 8-bit transceiver, 3-state output, 24mA drive current, 4.5V–5.5V supply, -40°C to 85°C operating range) and mechanical requirements (56-BSSOP package). All are ROHS3 compliant with MSL 1 rating.

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

A: Both series meet the specified electrical and mechanical parameters for this application. The 74ACT series substitutes (74ACT16543DLR, 74ACT16646DLR, 74ACT16657DLR) are active products, while 74FCT series substitutes (74FCT162652ATPVCT, CY74FCT162543TPVCT) are obsolete. For new designs, 74ACT series parts are preferred due to ongoing availability.

Q: Are there any package or pinout differences between the main part and substitutes?

A: No. All parts use the 56-BSSOP package with identical 0.295" width and 7.50mm dimensions. Surface mount compatibility is maintained across all substitutes without PCB redesign.

Q: Which substitute should be selected for long-term production?

A: 74ACT16543DLR, 74ACT16646DLR, or 74ACT16657DLR are recommended for long-term production due to active product status. These parts ensure sustained supply chain availability and manufacturer support.

Q: Are all substitutes RoHS compliant?

A: Yes. All substitute parts are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the compliance profile of the 74ACT16652DLRG4.
