Key Parameters

Substitute Part Grouping Explanation

Substitution for the 74LCX16652MEAX is determined by strict equivalence across the following critical parameters:

• Logic Function: Transceiver, Non-Inverting with 2 elements, 8 bits per element
• Output Configuration: 3-State output
• Drive Current: 24mA output high and low
• Supply Voltage Range: Minimum 1.65V to 3.6V (substitute parts support extended lower voltage)
• Operating Temperature: -40°C to 125°C (substitute parts support extended upper temperature)
• Mounting and Package: Surface mount, 56-pin SSOP or compatible variants

All identified substitutes are from the Texas Instruments 74LVCH16652 series, which maintains functional and electrical equivalence while offering active product status and RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

SN74LVCH16652ADL is the primary substitute for direct replacement of the 74LCX16652MEAX. This part maintains identical package geometry (56-BSSOP, 0.295" width), ensuring PCB layout compatibility without modification. The SN74LVCH16652ADL is active product status with ROHS3 compliance, providing long-term availability and regulatory alignment.

SN74LVCH16652ADGGR and SN74LVCH16652ADGVR are functionally equivalent alternatives with reduced package footprints (56-TFSOP variants). These options are suitable for space-constrained applications where PCB redesign is acceptable. Both maintain full electrical equivalence and active product status.

All three substitutes operate within the original supply voltage range and provide extended operating temperature capability (-40°C to 125°C versus -40°C to 85°C), enhancing thermal margin for demanding environments.

Frequently Asked Questions (FAQ)

Q: Can SN74LVCH16652ADL be used as a direct drop-in replacement for 74LCX16652MEAX?

A: Yes. The SN74LVCH16652ADL shares identical package dimensions (56-BSSOP, 0.295" width), pin configuration, and electrical specifications within the original operating range. No PCB modifications are required.

Q: What are the differences between the three Texas Instruments substitutes?

A: All three maintain functional and electrical equivalence. The primary difference is package footprint: SN74LVCH16652ADL uses 56-BSSOP (0.295" width), while SN74LVCH16652ADGGR uses 56-TFSOP (0.240" width) and SN74LVCH16652ADGVR uses 56-TFSOP (0.173" width). Packaging type also differs: ADL is supplied in Tube, while ADGGR and ADGVR are supplied in Tape & Reel.

Q: Are there voltage or temperature compatibility concerns?

A: No. The substitute parts support the original 2V to 3.6V supply range and extend the upper operating temperature limit to 125°C, providing enhanced thermal performance compared to the original 85°C specification.

Q: What is the impact of the obsolete status of 74LCX16652MEAX?

A: The obsolete status indicates discontinued manufacturing and declining inventory. Transitioning to an active substitute ensures long-term design support, procurement reliability, and compliance with current regulatory standards.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All three Texas Instruments substitutes are ROHS3 compliant, meeting current environmental and regulatory requirements. The original 74LCX16652MEAX is REACH unaffected but does not carry explicit RoHS3 certification.
