Substitute Part Grouping Explanation

Substitution of the 74AC16652DLRG4 is determined by strict equivalence across the following critical parameters:

• Logic type and function: Non-inverting transceiver configuration
• Element and bit architecture: 2 elements, 8 bits per element
• Output characteristics: 3-state output capability
• Electrical specifications: 24mA output current (high and low), 3V to 5.5V supply voltage range
• Temperature rating: -40°C to 85°C operating range
• Physical packaging: 56-BSSOP surface mount package with identical dimensions
• Compliance standards: ROHS3 compliance and MSL Level 1 rating

The 74AC16652DLR meets all these criteria and is identified as the manufacturer-recommended substitute. Both parts share the same base product number (74AC16652) and are functionally interchangeable within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

The 74AC16652DLR is the direct functional equivalent of the 74AC16652DLRG4. Both parts maintain identical electrical specifications, thermal ratings, and physical packaging dimensions. The primary distinction lies in product status and packaging format: the original part is discontinued while the substitute is classified as obsolete, and the substitute is supplied in Tape & Reel format rather than tube packaging.

For new designs or production replenishment, the 74AC16652DLR provides full compatibility with existing circuit designs utilizing the 74AC16652DLRG4. Both parts satisfy ROHS3 compliance requirements and carry MSL Level 1 moisture sensitivity ratings, ensuring equivalent reliability and environmental compliance in manufacturing and field deployment.

Frequently Asked Questions (FAQ)

Q: Are the 74AC16652DLRG4 and 74AC16652DLR electrically interchangeable?

A: Yes. Both parts are manufactured by Texas Instruments and share identical electrical specifications, including supply voltage range (3V to 5.5V), output current ratings (24mA), operating temperature range (-40°C to 85°C), and logic configuration (2-element, 8-bit non-inverting transceiver with 3-state output).
