SN74HCT574PWRG4

Flip Flops Overview

The SN74HCT574PWRG4 is an octal edge-triggered D-type flip-flop with three-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 delay of 22 ns at 5 V. It is housed in a 20-TSSOP package and supports surface-mount installation.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops for parallel data storage
• Three-state outputs designed specifically for efficient bus-driven architectures
• TTL voltage compatible inputs ensuring interoperability with standard logic families
• Non-inverting output polarity maintaining signal directionality without inversion

Flip Flops Applications

• Buffer register implementations requiring high-density data latching
• I/O port expansion circuits for microcontroller interfacing
• Bidirectional bus driver applications utilizing three-state control
• Working register stages in digital processing systems

Flip Flops Procurement Notes

Verify the G4 suffix indicates RoHS compliance and green manufacturing status as per Texas Instruments documentation. Confirm the TSSOP-20 package dimensions match your PCB footprint requirements. Ensure input voltage levels remain within TTL compatibility thresholds during operation. Check datasheet for specific thermal dissipation guidelines associated with the surface-mount package type.

Flip Flops Selection Notes

Select this component when TTL input compatibility is required alongside CMOS performance characteristics. The SN74HCT574PWRG4 is suitable for designs needing robust noise immunity at 5 V logic levels. Consider the 20-TSSOP package for space-constrained surface-mount assemblies. Evaluate the 22 ns typical propagation delay against your system timing constraints before finalizing the design.

Flip Flops Part Context

This part belongs to the SN74HCT574 family of octal edge-triggered D-type flip-flops. It shares functional similarities with the SN74HCT574PWR but includes the G4 suffix denoting environmental compliance. The device complements other Texas Instruments logic solutions by offering high drive capability and low power consumption in a compact surface-mount format.

Flip Flops Replacement Considerations

SN74HCT574PWR serves as a direct functional equivalent without the environmental suffix. SN74AHCT574PWR offers faster switching speeds while maintaining pin compatibility. SN74HC574PWR provides similar functionality with CMOS input thresholds instead of TTL compatibility.
