SN74AHC574DW

Flip Flops Overview

The SN74AHC574DW is an octal D-type flip-flop manufactured by Texas Instruments, featuring three-state outputs and non-inverting polarity. It operates within a supply voltage range of 2V to 5.5V and utilizes a 20-SOIC surface-mount package. The device exhibits a maximum propagation delay of 10.6ns at 5V with a 50pF load, supporting clock frequencies up to 115MHz. Output drive capability is specified at 8mA for both high and low states, with a static current consumption of 4µA. It functions reliably across a temperature range of -40°C to 85°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type edge-triggered flip-flops in a single integrated circuit.
• Three-state outputs enable direct connection to bus-oriented systems without additional buffer drivers.
• CMOS technology ensures low power consumption while maintaining high-speed performance characteristics.

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Register file storage elements in microprocessor systems
• Buffer memory applications for data latching
• General-purpose digital logic signal storage

Flip Flops Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and tape/reel specifications. Ensure compatibility with system voltage requirements and thermal operating conditions before integration. Cross-reference the component marking with official datasheets to authenticate source integrity and prevent counterfeit substitution.

Flip Flops Selection Notes

Select this component when an octal register with three-state output control is required for bus interfacing. The wide supply voltage range supports both 3.3V and 5V logic families. Consider the 20-SOIC package dimensions for PCB layout constraints and verify that the 115MHz clock frequency meets the target application timing requirements.

Flip Flops Part Context

This part belongs to the SN74AHC574 series of octal D-type flip-flops. It is functionally compatible with other variants in the family such as SN74AHC574DWR or SN74AHCT574DW, though input voltage thresholds may differ between AHC and AHCT logic families. The DW suffix specifically denotes the standard SOIC-20 plastic package format.

Flip Flops FAQ

What is the maximum clock frequency supported by the SN74AHC574DW?

The device supports a maximum clock frequency of 115MHz under standard operating conditions.

Does the SN74AHC574DW include an asynchronous clear function?

No, the standard SN74AHC574DW does not feature an asynchronous clear pin; it relies on clock-edge triggering for data capture.
