74LVC574ADTR2G

Overview

The MC74LVC574ADTR2G is an octal D-type flip-flop manufactured by onsemi, belonging to the LVC logic family. It features a single element with eight bits per element and operates within a supply voltage range of 2V to 3.6V. The device utilizes positive-edge triggering and provides non-inverting outputs. Key electrical parameters include a maximum propagation delay of 7ns at 3.3V with 50pF load, a clock frequency of 200 MHz, and output currents of 24mA for both high and low states. It is housed in a 20-TSSOP package and supports surface mount installation.

Feature Summary

• Octal D-type flip-flop architecture with positive-edge triggering mechanism
• High-speed performance supporting up to 200 MHz clock frequency
• Robust output drive capability with 24mA source and sink current
• Wide operating temperature range from -55°C to +125°C

Applications

• Parallel-to-serial data conversion circuits
• I/O port expansion in embedded systems
• Register file storage elements
• Buffering and latching applications in digital signal processing

Procurement Notes

Verify the specific suffix 'A' and 'DTR2G' against the manufacturer's official datasheet to confirm the exact pinout, tape-and-reel specifications, and RoHS compliance status. Ensure the ordering part number matches the required package type and moisture sensitivity level. Cross-reference the component marking code with the latest production documentation to avoid counterfeit or obsolete variants.

Selection Notes

Select this component when designing low-voltage (2V-3.6V) digital systems requiring high-speed data storage. The 200 MHz clock speed and 7ns propagation delay make it suitable for fast synchronous interfaces. Compare against HC series parts if higher noise immunity is needed, or LCX series for lower power consumption at reduced speeds. Ensure the 24mA output current meets the load requirements of the destination circuitry.

Part Context

This component belongs to the 74LVC574 family of octal D-type flip-flops. It is functionally similar to other industry-standard octal registers but optimized for low-voltage CMOS operation. The 'A' prefix typically denotes specific manufacturing revisions or enhanced specifications compared to standard versions. It serves as a core memory element in sequential logic designs.

Replacement Considerations

Public confirmed substitute part numbers include MC74LCX574DTR2G. Verify compatibility regarding voltage levels and output drive strength before substitution.
