MC74VHCT574AM

Flip Flops Overview

The MC74VHCT574AM is an octal D-type flip-flop with 3-state outputs, fabricated using advanced high-speed CMOS technology. It features VHCT logic compatibility, enabling direct interfacing with TTL and NMOS systems while maintaining low power consumption. The device includes a clock (CLK) input for data latching and an output enable (OE) control for bus driving applications.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops within a single package
• 3-state outputs allowing multiple devices to share data buses without interference
• VHCT logic compatibility ensures seamless integration with standard TTL and NMOS logic families

Flip Flops Applications

• Parallel-to-serial data conversion in communication interfaces
• Register storage for microprocessor memory addressing
• Bus driver circuits requiring level shifting between logic families

Flip Flops Procurement Notes

Verify the suffix 'AM' corresponds to the specific tape-and-reel packaging variant rather than tube packaging. Confirm RoHS compliance status through official onsemi documentation. Ensure the component matches the VHCT series specifications rather than standard HCT or VHC variants when designing for TTL compatibility.

Flip Flops Selection Notes

Select this component when interfacing high-speed CMOS logic with legacy TTL systems. The VHCT architecture provides faster switching speeds compared to standard HCT devices. Consider the 3-state output capability if bus arbitration is required in the system design.

Flip Flops Part Context

This part belongs to the MC74VHCT574A family of octal flip-flops. It shares pinout compatibility with LS574 devices but offers improved performance characteristics due to CMOS fabrication. The AM suffix typically denotes specific packaging configurations available from authorized distributors.

Flip Flops Replacement Considerations

MC74VHCT574A: Direct functional equivalent with potential packaging differences. MM74HCT574MTC: Alternative HCT series option with similar functionality but different speed and voltage characteristics.
