74ABT574CSCX

Flip Flops Overview

The Fairchild Semiconductor 74ABT574CSCX is an octal D-type flip-flop featuring 3-STATE outputs, housed in a 20-pin SOIC package. It operates within a supply voltage range of 2V to 6V and supports data rates up to 180 MHz. The device includes buffered common Clock (CP) and Output Enable (OE) inputs, ensuring synchronized data storage on the LOW-to-HIGH clock transition. Designed for high-speed applications, it offers low power consumption with ICC and IOZ reduced by 50% compared to standard AC/ACT logic families.

Flip Flops Feature Summary

• Octal D-type flip-flop architecture with 3-STATE outputs for bus-oriented applications
• Buffered common Clock and Output Enable inputs for simplified interface design
• High-speed operation supporting data rates up to 180 MHz
• Low power consumption with significantly reduced ICC and IOZ

Flip Flops Applications

• Microprocessor input or output port interfacing
• High-speed memory address drivers
• Clock driver circuits
• Bus-oriented transmitter/receiver systems

Flip Flops Procurement Notes

Verify the specific suffix 'CSCX' against the manufacturer's current datasheet to confirm package dimensions and tape-and-reel specifications. Ensure compatibility with the required operating temperature range and supply voltage levels before integration. Cross-reference the RoHS compliance status with the latest environmental declarations provided by Fairchild Semiconductor or its successor entity.

Flip Flops Selection Notes

Select this component when high-speed octal latching with 3-STATE control is required. It serves as a functional equivalent to the 74ACT374 but with a broadside pinout configuration, facilitating easier routing in dense PCB layouts. Consider the 2V to 6V operating range and TTL-compatible inputs if interfacing with mixed-voltage logic systems.

Flip Flops Part Context

The 74ABT574 belongs to the ABT logic family, which combines the speed of Advanced CMOS with TTL-compatible inputs. This specific part number represents the surface-mount variant in a 20-SOIC package. It is functionally identical to the 74AC574 and 74ACT574 but optimized for lower power dissipation while maintaining high performance suitable for modern digital systems.

Flip Flops Replacement Considerations

The 74ABT574CSCX is functionally interchangeable with the 74ACT574CSCX and 74AC574CSCX due to identical logical operations. However, verify voltage level compatibility and switching speed requirements, as the ACT and AC variants may differ in drive strength and power characteristics compared to the ABT series.
