74VHC574MTR

Overview

The STMicroelectronics 74VHC574MTR is an octal D-type flip-flop with three-state non-inverting outputs, fabricated using advanced sub-micron silicon gate C2MOS technology. It operates within a voltage range of 2V to 5.5V and features a maximum clock frequency of 180 MHz at 5V. The device exhibits low power dissipation with a maximum static current of 4 µA and symmetrical output impedance providing 8 mA drive capability. Propagation delays are balanced, and it includes power-down protection on inputs for enhanced noise immunity.

Procurement Notes

Verify the specific ordering suffix 'MTR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the component status aligns with current production lifecycle requirements, as availability may vary based on manufacturer allocation. Ensure compatibility with existing PCB footprints and design rules before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring octal storage with high-speed performance up to 180 MHz. It is suitable for applications demanding low power consumption and robust noise immunity within a 2V to 5.5V supply range. Consider its pin compatibility with standard 74-series logic families if migrating from older designs or requiring direct replacement in legacy architectures.

Part Context

This part belongs to the 74VHC series, representing advanced high-speed CMOS logic. It is functionally compatible with the standard 74LS574 but offers significantly faster switching speeds and lower power dissipation. The M74VHC574 variant shares similar electrical characteristics but may differ in package options or manufacturing revisions.

Replacement Considerations

Direct substitutes include the 74VHC574T and 74VHC574TR from STMicroelectronics, which share identical logical functions and pinouts. Other manufacturers offering equivalent octal D-type flip-flops with three-state outputs should be evaluated for voltage range and speed compatibility.
