Overview
The AD8564ARUZ-REEL is a quad comparator featuring separate analog and digital supply sections. It operates from a single 5 V supply or dual ±5 V supplies. The device provides a propagation delay of 7 ns typical, with a maximum of 9.8 ns at 25°C. Input offset voltage is typically 7 mV, and input bias current is ±4 μA. Digital outputs are CMOS/TTL compatible, delivering up to 40 mA output current. Operating temperature range is -40°C to +125°C.
Feature Summary
- Separate analog and digital power supply sections for independent operation
- TTL and CMOS logic-compatible digital outputs
- High-speed performance with 7 ns typical propagation delay
- Wide output swing capability
Applications
- High speed timing circuits
- Line receivers
- Data communications systems
- High speed sampling systems
- Window comparators
Procurement Notes
Verify the specific package type matches the RU-16 (TSSOP) designation in the ordering guide. Confirm RoHS compliance status via the suffix 'Z' if required by project specifications. Ensure the reel packaging aligns with automated assembly requirements. Cross-reference the revision history to confirm the datasheet version matches the component batch.
Selection Notes
Select this component when high-speed switching is required alongside noise immunity provided by separate supply rails. The pinout is compatible with MAX901 designs, facilitating direct upgrades. Consider the input common-mode range limitations relative to the positive supply rail when designing signal interfaces. Evaluate thermal resistance values for the TSSOP package under expected load conditions.
Part Context
This part belongs to the AD8564 family of quad comparators manufactured by Analog Devices. It is designed for applications requiring fast response times and flexible power configurations. The family includes variants in PDIP, SOIC, and TSSOP packages. The AD8564 serves as a high-performance alternative to older comparator generations in data communication and timing applications.
Replacement Considerations
The AD8564 is pin-compatible with the MAX901. Designers upgrading from MAX901 should verify that the lower supply currents of the AD8564 meet system power budgets. No other direct substitutes are documented in the official ordering guide.
