MC74AC374MELG

Flip Flops Overview

The MC74AC374MELG is an octal D-type flip-flop manufactured by onsemi, belonging to the 74AC logic series. It features eight positive-edge-triggered D-type inputs with corresponding Q outputs and a single clock input. The device provides three-state outputs controlled by an active-low output enable pin. It operates within a supply voltage range of 2V to 6V. Key electrical parameters include a maximum propagation delay of 9.5ns at 5V with 50pF load, a clock frequency of 155MHz, and static current of 8µA. Output drive capability is specified at 24mA for both high and low states. The component is housed in a 20-SOEIAJ surface-mount package.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops within a single integrated circuit
• Three-state outputs allowing direct bus driving connections through an active-low enable control
• Positive-edge triggering mechanism synchronized by a single common clock input line
• CMOS construction ensuring low power consumption alongside high-speed operational performance

Flip Flops Applications

• Parallel-to-serial data conversion circuits requiring temporary storage buffers
• Register arrays for microprocessor interface data latching operations
• General-purpose shift register configurations for signal processing chains
• Memory address buffering systems in embedded controller architectures

Flip Flops Procurement Notes

Verify component authenticity through authorized distributors as this part number may be discontinued or obsolete. Confirm package compatibility with existing PCB footprints, specifically the 20-SOEIAJ dimensions. Review manufacturer product change notifications for any revisions affecting pinout or electrical characteristics. Ensure supply chain sources provide valid traceability documentation before integration into production designs.

Flip Flops Selection Notes

Select this component when designing systems requiring octal storage with tri-state bus interfacing capabilities. Consider the 2V to 6V operating range for compatibility with various logic levels. Evaluate the 9.5ns propagation delay against system timing requirements. Compare against similar 74AC series devices if specific package variations or alternative manufacturers are preferred for supply chain diversification.

Flip Flops Part Context

This device belongs to the widely adopted 74AC family of high-speed CMOS logic components. It serves as a standard solution for digital storage applications requiring multiple flip-flops in a compact form factor. The octal architecture simplifies board layout by consolidating eight storage elements into one package, reducing component count compared to individual single-bit flip-flops.

Flip Flops Replacement Considerations

Public confirmed substitute part numbers include MC74AC374DWR2G from onsemi. Other compatible alternatives identified in market data include SN74AC374NSR from Texas Instruments and CD74AC374M from Texas Instruments. Verify pinout and electrical specifications match before substitution.
