Key Parameters

Substitute Part Grouping Explanation

Substitution of the AD8564ARU-REEL is determined by strict equivalence across the following critical parameters:

• Channel Configuration: 4-channel general-purpose comparator architecture
• Output Compatibility: CMOS and TTL output types
• Electrical Performance: Input offset voltage (7mV @ 5V), input bias current (4µA @ 5V), quiescent current specifications, CMRR (85dB), PSRR (80dB), and propagation delay (9.8ns)
• Package Specification: 16-TSSOP surface-mount package with identical physical dimensions (0.173", 4.40mm Width)
• Operating Temperature Range: -40°C ~ 85°C
• Moisture Sensitivity: MSL 1 (Unlimited)

The AD8564ARUZ-REEL qualifies as a direct substitute based on identical electrical specifications, package configuration, and functional equivalence. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

• Packaging Format: Available in Cut Tape (CT) and Digi-Reel® packaging, providing flexibility for both prototype and production-volume applications

Selection between these parts should be based on procurement availability, supply chain requirements, and compliance mandates specific to the end application.

Frequently Asked Questions (FAQ)

Q: Can the AD8564ARUZ-REEL be used as a direct replacement for the AD8564ARU-REEL?

A: Yes. Both parts are electrically and functionally identical. They share the same channel count (4), output types (CMOS, TTL), electrical specifications, and 16-TSSOP package configuration. The primary difference is product status and regulatory compliance documentation.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: The AD8564ARU-REEL is classified as Obsolete, indicating that Analog Devices Inc. no longer manufactures this variant. The AD8564ARUZ-REEL maintains Active status, ensuring continued production, technical support, and long-term availability. For new designs and ongoing procurement, the Active variant is recommended.

Q: Are there any package or mounting differences between these parts?

A: No. Both parts use the identical 16-TSSOP surface-mount package with 0.173" width and 4.40mm dimensions. PCB footprints, land patterns, and assembly processes are fully compatible.

Q: What compliance certifications apply to each part?

A: The AD8564ARU-REEL specifications do not include explicit RoHS or REACH documentation in the provided data. The AD8564ARUZ-REEL is ROHS3 Compliant and REACH Unaffected, meeting current environmental and chemical safety regulations.

Q: Are the electrical performance characteristics identical?

A: Yes. Input offset voltage, input bias current, quiescent current, CMRR, PSRR, propagation delay, and operating temperature range are identical across both parts. No performance trade-offs exist between the two variants.

Q: What packaging formats are available for the AD8564ARUZ-REEL?

A: The AD8564ARUZ-REEL is supplied in Cut Tape (CT) and Digi-Reel® packaging formats, accommodating both prototype development and high-volume production workflows.
