SN74HCT574PWT

Flip Flops Overview

The SN74HCT574PWT is an octal edge-triggered D-type flip-flop with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL-compatible inputs. The device provides non-inverting outputs capable of driving bus lines or up to 15 LSTTL loads, with typical propagation delays of 22 ns at 5 V. It is housed in a 20-TSSOP package.

Flip Flops Feature Summary

• Octal edge-triggered D-type flip-flops with 3-state outputs
• TTL voltage compatible inputs
• Directly drives bus lines or multiple LSTTL loads

Flip Flops Applications

• Buffer registers
• I/O ports
• Bidirectional bus drivers
• Working registers

Flip Flops Procurement Notes

Verify the specific suffix 'PWT' against official Texas Instruments documentation to confirm the tape-and-reel packaging configuration. Ensure the logic family designation matches system requirements for HCT compatibility. Cross-reference the RoHS status and lead-free markings directly from the manufacturer's current datasheet to guarantee compliance with project specifications.

Flip Flops Selection Notes

Select this component when designing systems requiring eight synchronized data latches with tri-state control. It is suitable for applications needing direct interface with TTL logic levels while maintaining CMOS low power characteristics. Consider the 20-TSSOP package constraints for PCB layout and thermal management during selection.

Flip Flops Part Context

This part belongs to the SN74HCT574 series of octal flip-flops. It shares functional similarities with other variants like SN74AHCT574 but differs in speed and voltage specifications. The PWT suffix indicates a specific reel-based packaging format distinct from tube-packaged versions like SN74HCT574PW.

Flip Flops Replacement Considerations

SN74HCT574PW is a pin-compatible alternative in tube packaging. SN74AHCT574PWRG4 offers faster switching speeds within the same voltage range.
