MM74HC574MTCX

Flip Flops Overview

The MM74HC574MTCX is an octal D-type edge-triggered flip-flop manufactured by onsemi, belonging to the HC logic series. It features a single-ended input and three-state non-inverting output configuration housed in a 20-TSSOP surface-mount package. The device operates within a supply voltage range of 2 V to 6 V and supports a maximum clock frequency of 35 MHz. Key electrical parameters include a propagation delay of 155 ns, with high-level and low-level output currents rated at -7.8 mA and 7.8 mA respectively. The component functions across an operating temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Octal D-type edge-triggered flip-flop architecture providing eight independent data storage elements.
• Three-state outputs enable direct bus line driving without external buffer requirements.
• Non-inverting polarity ensures logical consistency between input data and stored output states.

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Register file implementation for microprocessor interfaces
• General-purpose digital signal buffering

Flip Flops Procurement Notes

Verify the specific suffix 'MTCX' corresponds to the TSSOP-20 package and reel packaging format as documented. Confirm RoHS compliance status through official manufacturer declarations prior to integration. Ensure design compatibility with the specified 2V to 6V operating voltage window and -40°C to +85°C temperature range constraints.

Flip Flops Selection Notes

Select this component when an octal register with three-state outputs is required within the HC logic family. Consider the 155 ns propagation delay and 35 MHz clock limit against system timing requirements. Evaluate the 20-TSSOP footprint against available PCB space and thermal management needs compared to alternative packages like SOIC.

Flip Flops Part Context

This part belongs to the MM74HC574 series of octal D-type flip-flops produced by onsemi. It shares functional similarities with other variants such as MM74HC574SJX and MM74HC574MTC, differing primarily in packaging style and manufacturing lot specifications. The HC series provides standard CMOS performance characteristics suitable for general digital logic applications.
