AD8564ARZ-REEL

Overview

The AD8564ARZ-REEL is a quad analog comparator manufactured by Analog Devices Inc. It features separate analog and digital power supplies, enabling operation from ±5 V dual supplies or a 5 V single supply while maintaining CMOS/TTL-compatible outputs. The device offers a typical propagation delay of 7 ns with a maximum of 9.8 ns under specified conditions. Key electrical parameters include an input offset voltage of up to 7 mV, input bias current of ±4 μA, and output drive capability of 40 mA. It operates within an industrial temperature range of -40°C to +125°C and is housed in a 16-lead narrow body SOIC package.

Feature Summary

• Features separate analog and digital supply sections for independent operation and protection against supply pin interaction.
• Provides TTL/CMOS logic-compatible outputs with wide output swing capabilities.
• Delivers fast 7 ns propagation delay with matched rising and falling signal delays over temperature and voltage.
• Supports low power consumption suitable for battery-operated instrumentation.

Applications

• High speed timing circuits
• Line receivers
• Data communications systems
• High speed V-to-F converters
• Window comparators

Procurement Notes

Verify the specific ordering suffix to confirm the package type and reel configuration. Ensure the component meets RoHS compliance requirements if applicable to your manufacturing process. Confirm that the supplier provides valid traceability documentation for the Analog Devices part number. Check for any specific handling instructions related to ESD sensitivity during storage and assembly.

Selection Notes

Select this component when high-speed comparison with matched rise/fall delays is required. The separate digital supply allows flexibility in interfacing with different logic families. Consider the 16-lead SOIC package for surface-mount applications requiring moderate pin density. Evaluate thermal resistance specifications if operating at the upper limits of the industrial temperature range.

Part Context

This part belongs to the AD8564 family of quad comparators designed for general-purpose high-speed applications. It serves as a direct upgrade for MAX901 designs with lower supply currents. The device is pin-compatible with other industry-standard comparators but offers distinct advantages through its split-supply architecture and precise delay tracking characteristics across varying environmental conditions.

Replacement Considerations

The AD8564 is explicitly noted as a pin-compatible upgrade for MAX901 designs. Verify functional equivalence regarding propagation delay and output drive capabilities when substituting. Ensure that the replacement part supports the same separate analog and digital supply configurations required by the original circuit design.
