MC74ACT574MG

Flip Flops Overview

The MC74ACT574MG is an octal D-type flip-flop with 3-state outputs manufactured by onsemi. It belongs to the 74ACT logic series and utilizes silicon gate CMOS technology. The device operates within a supply voltage range of 4.5 V to 5.5 V. It features a propagation delay of 11 ns at 5 V with a 50 pF load. Output drive capability is specified as -24 mA for high level and 24 mA for low level. The component is housed in a SOIC-J-20 surface-mount package and supports operation across a temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops within a single integrated circuit.
• Three-state output architecture allowing direct bus driving connections without external buffers.
• Positive-edge triggering mechanism synchronized with clock signal transitions.
• Non-inverting polarity ensuring output data matches input state upon clock activation.

Flip Flops Applications

• Register files in microprocessor-based systems
• Parallel-to-serial data conversion circuits
• Isolation buffers for system bus architectures
• Timing control logic in digital communication interfaces

Flip Flops Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm package type and tape/reel specifications. Ensure compatibility with standard JEDEC footprints for the SOIC-J-20 form factor during PCB layout. Confirm RoHS compliance status through current environmental declarations prior to final procurement authorization.

Flip Flops Selection Notes

Select this component when designing 5V CMOS logic systems requiring high-speed data storage with bus-compatible outputs. The 74ACT series offers performance levels comparable to LS TTL while maintaining CMOS power efficiency. Evaluate the 11 ns propagation delay against system timing requirements to ensure adequate setup and hold times are met for reliable operation.
