SN74BCT574DWR

Flip Flops Overview

The SN74BCT574DWR is an octal transparent D-type flip-flop manufactured by Texas Instruments, housed in a 20-SOIC surface-mount package. It features three-state outputs designed for driving highly capacitive loads or multiple bus loads. The device operates within a supply voltage range of 2.7V to 3.6V and supports a maximum clock frequency of 153 MHz. Key electrical parameters include a typical propagation delay of 4.3 ns at 5V with 50pF load, static current of 4 µA, and output drive capabilities of ±24 mA. It functions as a buffer register, I/O port, or working register in digital systems.

Flip Flops Feature Summary

• Octal transparent D-type flip-flop architecture with three-state outputs
• Designed specifically for driving highly capacitive or relatively heavy bus loads
• Compatible with standard CMOS logic families across the specified voltage range

Flip Flops Applications

• Buffer registers in data acquisition systems
• I/O port expansion for microcontroller interfaces
• Working registers in high-speed digital processing circuits

Flip Flops Procurement Notes

Verify the specific ordering suffix to ensure the correct package variant and tape/reel configuration match your assembly requirements. Confirm that the supply voltage range aligns with your system's 3.3V or 5V logic levels, as this component is optimized for low-voltage operation. Check RoHS compliance status if environmental regulations apply to your manufacturing process.

Flip Flops Selection Notes

Select this component when an octal storage element with strong drive capability is required for bus applications. It is suitable for designs needing transparency during enable periods and high-impedance states otherwise. Consider the 153 MHz clock speed for timing constraints. Ensure the SOIC-20 footprint matches your PCB layout constraints compared to other package options like TSSOP.

Flip Flops Part Context

This part belongs to the BCT (Bus Clock Technology) family from Texas Instruments, which combines the performance of advanced CMOS technology with TTL-compatible inputs. It is functionally similar to the SN74BCT574DW but differs in packaging. The DWR suffix indicates the 20-pin Small Outline Integrated Circuit (SOIC) package with a 7.50mm width, optimized for automated surface-mount assembly processes.

Flip Flops Replacement Considerations

SN74BCT574DW is a pin-to-pin compatible alternative in a different package. SN74AHCT574DWR offers similar functionality but with different voltage and speed characteristics.
