MC74F174M

Flip Flops Overview

The MC74F174M is a high-speed silicon-gate CMOS logic device belonging to the Fairchild Semiconductor (now onsemi) 74F series. It functions as a positive-edge-triggered D-type flip-flop with six independent elements per chip, providing non-inverting outputs. The component operates within a supply voltage range of 4.5V to 5.5V and supports clock frequencies up to 80 MHz. It features a maximum propagation delay of 10ns at 5V with a 50pF load. Designed for surface-mount applications, it utilizes a 16-pin Small Outline Integrated Circuit (SOIC) package.

Flip Flops Procurement Notes

Verify the specific manufacturer suffix and package variant against current datasheets, as legacy components may have multiple revisions or obsolete statuses. Confirm that the 74F series specifications align with system requirements regarding power consumption and noise immunity before finalizing procurement decisions.

Flip Flops Selection Notes

Select this component when high switching speed is prioritized over low power consumption, as the 74F series typically draws higher quiescent current compared to HC or LV families. Ensure the design environment supports the 5V logic levels and that the PCB layout accommodates the thermal characteristics associated with faster switching speeds in surface-mount packages.

Flip Flops Part Context

This part belongs to the broader 74F logic family, known for its superior speed performance relative to standard TTL and earlier CMOS technologies. It serves as a fundamental building block for sequential logic circuits where rapid data latching is critical. The device represents a transition era in semiconductor manufacturing, bridging discrete transistor designs with advanced CMOS integration.

Flip Flops Replacement Considerations

Direct substitutes include the SN74F174AN from Texas Instruments. Verify pinout compatibility and electrical parameter equivalence before substitution.
