SN74AHC574PWRG4

Flip Flops Overview

The SN74AHC574PWRG4 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 2 V to 6 V and features a wide operating temperature range from -40°C to 125°C. The device utilizes a 20-pin TSSOP package for surface-mount installation. Key electrical specifications include a maximum propagation delay of 8 ns at 5 V with 50 pF load, a clock frequency of up to 115 MHz, and output drive currents of ±8 mA. Static current consumption is typically 4 µA.

Flip Flops Feature Summary

• Provides eight independent D-type flip-flops with positive-edge triggering for parallel data storage.
• Features three-state outputs that allow direct connection to bus-oriented systems without external buffers.
• Compatible with standard CMOS logic families while maintaining TTL-compatible input thresholds.

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Register files in microprocessor-based systems
• Buffering and latching operations on system buses

Flip Flops Procurement Notes

Verify the complete part number including the G4 suffix to confirm RoHS compliance and green manufacturing status. Ensure the ordering quantity aligns with standard reel sizes specified in the manufacturer's documentation. Confirm package dimensions match the design footprint requirements before finalizing procurement.

Flip Flops Selection Notes

Select this component when designing systems requiring high-speed data latching with low power consumption. The AHC series offers faster switching speeds compared to standard HC or HCT variants. Verify that the system voltage falls within the 2 V to 6 V operational range and that the thermal environment supports the extended industrial temperature rating.

Flip Flops Part Context

This component belongs to the Texas Instruments SN74AHC family of advanced high-speed CMOS logic devices. The AHC series is designed to provide performance improvements over previous generations while maintaining compatibility with standard CMOS inputs. The PWRG4 designation indicates a specific tape-and-reel packaging configuration with lead-free and halogen-free attributes.

Flip Flops Replacement Considerations

SN74AHCT574PWRG4: Offers TTL-compatible inputs instead of CMOS-compatible inputs while maintaining similar speed and package characteristics. SN74AHC574PW: Identical functional specification but may differ in environmental compliance or manufacturing origin depending on the suffix.
