SN74AHCT574DGVR

Flip Flops Overview

The SN74AHCT574DGVR is an octal edge-triggered D-type flip-flop with three-state outputs manufactured by Texas Instruments. It belongs to the SN74AHCT series, featuring TTL-compatible inputs and CMOS technology. The device operates within a supply voltage range of 4.5 V to 5.5 V. It provides non-inverting outputs capable of driving bus lines or multiple loads. The component is housed in a 20-pin TVSOP package designed for surface-mount applications.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops in a single integrated circuit
• Three-state outputs allowing direct connection to bus structures without external buffers
• TTL-compatible input logic levels ensuring interoperability with standard TTL systems
• Edge-triggered data storage synchronized by positive clock transitions

Flip Flops Applications

• Buffer registers for temporary data storage in digital circuits
• I/O ports for interfacing microprocessors with peripheral devices
• Bidirectional bus drivers for managing data flow on system buses
• Working registers within embedded control systems

Flip Flops Procurement Notes

Verify the specific suffix 'DGVR' corresponds to the TVSOP-20 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design compatibility with the specified 4.5 V to 5.5 V operating voltage range. Validate thermal performance requirements against the datasheet specifications for the selected package type.

Flip Flops Selection Notes

Select this component when TTL-compatible inputs are required alongside high-speed CMOS performance. The AHCT series bridges the gap between legacy TTL systems and modern low-power CMOS designs. Consider the TVSOP-20 package dimensions for PCB layout constraints. Evaluate propagation delay characteristics against system timing requirements to ensure signal integrity across the octal register array.

Flip Flops Part Context

This part is a member of the Texas Instruments SN74AHCT family, which combines the speed of AHC logic with HCT input compatibility. It serves as a standard solution for parallel data storage and transfer in mixed-voltage environments. The device replaces older discrete flip-flop implementations, reducing board space and assembly complexity while maintaining reliable digital signal processing capabilities.

Flip Flops Replacement Considerations

SN74AHCT574DR is available in a SOIC-20 package with identical electrical characteristics. SN74AHCT574PW offers a TSSOP-20 alternative with compatible pinout and functionality. Verify package footprint differences before substituting these variants in existing designs.
