SN74BCT574DW

Flip Flops Overview

The SN74BCT574DW is an octal D-type flip-flop with 3-state outputs manufactured by Texas Instruments. It belongs to the BCT logic series, utilizing BiCMOS technology for high-speed performance. The device features non-inverting polarity and operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a maximum propagation delay of 8.2 ns at 5 V, a low-level output current of 32 mA, and a high-level output current of -15 mA. It functions in a temperature range of 0°C to +70°C and is housed in a 20-pin SOIC package.

Flip Flops Feature Summary

• Octal D-type flip-flop architecture with 3-state outputs
• BiCMOS technology for enhanced speed and drive capability
• Non-inverting data path configuration

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Register storage in digital systems
• Buffering of bus signals

Flip Flops Procurement Notes

Verify the manufacturer part number SN74BCT574DW against official Texas Instruments documentation to confirm authenticity. Ensure the component matches the specified SOIC-20 package and BCT logic family characteristics. Cross-reference technical parameters such as voltage ranges and propagation delays with the official datasheet to guarantee compatibility with system requirements before procurement.

Flip Flops Selection Notes

Select this component when an octal register with 3-state output control is required in designs operating at 5V. The BCT series offers superior switching speeds compared to standard 74LS logic while maintaining compatible pinouts. Consider the 32 mA sink current capability for driving moderate loads. Verify that the application environment stays within the 0°C to +70°C commercial temperature range.

Flip Flops Part Context

This part is part of the SN74BCT family of BiCMOS logic devices from Texas Instruments. It serves as a digital storage element within the broader category of flip-flops and latches. The DW suffix indicates a plastic small-outline package (SOIC) variant, distinguishing it from through-hole or tape-and-reel versions like the DWR.

Flip Flops Replacement Considerations

Compatible substitutes include the SN74BCT574N (PDIP package) and SN74BCT574DWR (SOIC-20 tape and reel). These alternatives share identical logical functionality and pinout configurations but differ in packaging style and manufacturing lot specifications.
