MC74ACT574DW

Flip Flops Overview

The MC74ACT574DW is an octal D-type flip-flop from the 74ACT logic series, manufactured by onsemi. It features eight positive-edge-triggered D-type latches with three-state outputs 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 11 ns and output drive currents of ±24 mA. It supports single-ended inputs and non-inverting polarity, functioning reliably across an industrial 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 outputs allowing direct connection to bus systems for efficient data transfer
• CMOS technology ensuring high noise immunity and low static power consumption

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Register storage in microprocessor-based systems
• Buffering and latch applications in digital logic designs

Flip Flops Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as historical records indicate potential variations. Ensure the specific suffix matches the required packaging format. Check for moisture sensitivity level requirements if surface-mount assembly is planned. Validate that the part number corresponds to the active manufacturing version rather than obsolete variants.

Flip Flops Selection Notes

Select this component when designing 5V CMOS logic systems requiring octal storage with high-speed performance. The ACT series offers faster switching speeds compared to standard AC counterparts while maintaining compatible pinouts. Consider the 20-SOIC package dimensions for PCB layout constraints. Evaluate the ±24 mA drive capability against load requirements to ensure signal integrity without additional buffering stages.

Flip Flops Part Context

This part belongs to the widely adopted 74ACT family, bridging the performance gap between older TTL standards and modern CMOS technologies. It serves as a fundamental building block for sequential logic design. The octal architecture allows for compact implementation of complex state machines and data registers in embedded control applications.
