74FCT374ASCX

Flip Flops Overview

The 74FCT374ASCX is an octal D flip-flop manufactured by National Semiconductor, now part of Texas Instruments. It features TRI-STATE outputs suitable for bus-oriented applications. The device operates within a temperature range of 0°C to 70°C and is supplied in 13-inch reels. It utilizes a 20-pin Small Outline Integrated Circuit (SOIC) package with a width of 0.295 inches.

Flip Flops Feature Summary

• Octal D flip-flop architecture with TRI-STATE outputs
• Buffered positive edge-triggered clock input
• Common Output Enable control for all flip-flops

Flip Flops Applications

• Bus-oriented data storage systems
• Digital logic circuit design
• Microprocessor interface circuits

Flip Flops Procurement Notes

Verify the manufacturer designation carefully, as National Semiconductor was acquired by Texas Instruments. Confirm the specific suffix 'ASCX' matches your required package type and tape-and-reel specifications. Ensure the component status is current, as older series may be obsolete or replaced by newer equivalents from the FCT family.

Flip Flops Selection Notes

Select this component when an octal D-type flip-flop with TRI-STATE capability is required for bus applications. Consider the 0°C to 70°C operating temperature range for standard commercial environments. Verify that the 20-pin SOIC package fits your PCB layout constraints and that the voltage levels are compatible with your system logic standards.

Flip Flops Part Context

This component belongs to the 74FCT logic family, designed for high-speed CMOS applications with TTL-compatible inputs. The 74FCT374 variant specifically provides eight independent D flip-flops with output enable controls. It serves as a fundamental building block for sequential logic circuits requiring parallel data storage and tri-state bus interfacing capabilities.

Flip Flops Replacement Considerations

Public confirmed substitute part numbers include 74FCT374AFMQR and 74FCT374ALCQR. These alternatives share the same functional description of an octal D flip-flop with TRI-STATE outputs. Verify pinout compatibility and package dimensions before substitution.
