MM74HCT574SJ

Flip Flops Overview

The MM74HCT574SJ is an octal D-type flip-flop manufactured by onsemi, belonging to the HCT logic series. It features eight non-inverting outputs with three-state capability, housed in a 20-SOIC package. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a maximum propagation delay of 30 ns at 5 V with 50 pF load, and output drive currents of -7.2 mA (high) and 7.2 mA (low). It supports surface-mount installation and functions across a temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Provides octal data storage with positive edge-triggered clocking for reliable state capture.
• Integrates three-state outputs to facilitate bus-oriented architectures and system isolation.
• Ensures CMOS compatibility with standard TTL loads through HCT input threshold specifications.

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Bus interface modules requiring isolated storage
• Digital control systems utilizing register arrays

Flip Flops Procurement Notes

Verify the specific suffix 'SJ' against official manufacturer documentation to confirm package dimensions and tape/reel specifications. Ensure compliance with RoHS directives and moisture sensitivity levels as defined in the latest datasheet revision. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Confirm that the ordering code matches the exact pinout and electrical characteristics required for the target application design.

Flip Flops Selection Notes

Select this component when designing systems requiring 5 V logic compatibility with robust noise immunity. The HCT series ensures direct interfacing with LSTTL loads without additional buffering. Consider the SOIC-20 package for applications needing moderate pin density with surface-mount assembly. Evaluate thermal performance within the specified operating temperature range to ensure long-term reliability in industrial environments.

Flip Flops Part Context

This component belongs to the MM74HCT574 family of octal D-type flip-flops. It shares functional similarities with other variants like MM74HCT574WM and MM74HCT574MTC, differing primarily in packaging style such as SOIC versus TSSOP. The family provides standardized timing and electrical characteristics suitable for general-purpose digital logic applications requiring high-speed data latching.
