MC74HC574ADWR2

Flip Flops Overview

The MC74HC574ADWR2G is an octal D-type flip-flop with three-state outputs, manufactured by onsemi. It operates within a supply voltage range of 2.0 V to 6.0 V and features a propagation delay of 160 ns. The device provides high-level output current of -7.8 mA and low-level output current of 7.8 mA. It is housed in a 20-SOIC package and supports surface-mount installation. The component functions as a non-inverting logic element, clocked on the rising edge, suitable for digital data storage applications.

Flip Flops Feature Summary

• Octal configuration with three-state non-inverting outputs
• CMOS technology compatible with standard CMOS and LSTTL loads
• Data latching triggered by the positive edge of the clock signal
• High-impedance state control via Output Enable input

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Register banks for microprocessor interfaces
• Digital signal processing data buffering
• Memory address latching systems

Flip Flops Procurement Notes

Verify the suffix 'G' indicates RoHS compliance and lead-free status. Confirm the 'ADWR2' designation corresponds to the SOIC-20 surface mount package variant. Ensure moisture sensitivity level 3 handling procedures are followed during assembly. Cross-reference the specific ordering code with manufacturer documentation to confirm availability and revision history prior to final procurement decisions.

Flip Flops Selection Notes

Select this component when an octal latch with tri-state capability is required for 2V to 6V logic systems. It serves as a pin-compatible alternative to LS574 devices while offering lower power consumption typical of HC series CMOS. Consider the 160 ns propagation delay for timing constraints. Ensure the design accommodates the single-ended input and output structure for proper board layout and signal integrity.

Flip Flops Part Context

This part belongs to the 74HC family of high-speed CMOS logic devices. It shares functional similarities with the MC74HC374A but differs in pinout orientation to facilitate printed circuit board layout. The device integrates 266 FETs or 66.5 equivalent gates, providing robust performance for general-purpose digital logic applications requiring reliable data storage and transfer capabilities.

Flip Flops Replacement Considerations

MC74HC574ADWR2G is the RoHS-compliant version of the MC74HC574ADWR2. Direct substitutes include other manufacturers' 74HC574 variants in SOIC-20 packages, such as those from NXP or Nexperia, provided they meet the same electrical specifications and pinout requirements.
