DM74ALS574AWMX

Overview

The DM74ALS574AWMX is an octal D-type flip-flop manufactured by onsemi (formerly Fairchild Semiconductor). It features positive-edge triggering and three-state non-inverting outputs. The device operates within a supply voltage range of 4.5V to 5.5V. Key electrical parameters include a maximum propagation delay of 14ns at 5V with 50pF load, a clock frequency of 35 MHz, and static current consumption of 18 mA. Output drive capabilities are specified as 2.6mA for high state and 24mA for low state. It is housed in a 20-SOIC package.

Feature Summary

Positive-edge triggered D-type configuration for reliable data latching
Three-state non-inverting outputs allowing bus isolation
Advanced Low-power Schottky technology for enhanced performance

Applications

Register storage in microprocessor systems
Data buffering for memory interfaces
Asynchronous bidirectional data buses

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance and lead-free specifications against the original datasheet. Check moisture sensitivity level ratings prior to surface mount assembly. Validate package dimensions against SOIC-20 standards to ensure board compatibility.

Selection Notes

Select this component for applications requiring octal storage with tri-state control. Ensure operating temperature ranges align with industrial requirements. Compare propagation delays against system timing constraints. Verify output current capabilities match load requirements for proper signal integrity.

Part Context
