Key Parameters

Substitute Part Grouping Explanation

Substitution of the AD8564AR-REEL is determined by strict equivalence across the following critical parameters:

• Base product number (AD8564 family)
• Number of comparator elements (4)
• Output type (CMOS, TTL)
• Electrical specifications (input offset, bias current, quiescent current, CMRR, PSRR, propagation delay)
• Operating temperature range (-40°C ~ 85°C)
• Package type (16-SOIC surface mount)
• Moisture sensitivity level (MSL 1)

The AD8564ARZ-REEL qualifies as a direct substitute based on identical electrical performance, package configuration, and functional architecture. The primary distinction is packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The AD8564ARZ-REEL is the direct substitute for the AD8564AR-REEL. Both devices are electrically and functionally identical, with identical pin configurations and performance specifications across all measured parameters.

The AD8564ARZ-REEL is preferred for new designs and ongoing production due to its active product status. This part carries ROHS3 compliance and REACH unaffected certification, meeting current regulatory requirements for electronic component manufacturing and distribution.

The AD8564AR-REEL, classified as obsolete, should be replaced with the AD8564ARZ-REEL in production environments. Existing inventory of the obsolete part may be used in legacy system maintenance where supply continuity is not a concern.
