Product details

Device identity and active lifecycle

The Texas Instruments 54174FM is a D flip-flop built on TTL logic, a workhorse part for latching and edge-triggered storage in legacy and industrial logic chains. Its lifecycle status is Active, meaning the manufacturer continues to support production — no end-of-life notice or last-time-buy window is in effect.

RoHS compliance flag for BOM review

The 54174FM is RoHS non-compliant, a critical detail for any bill of materials that must meet RoHS directives — verify your exemption or accept the lead-bearing finish before committing the line.

Frequently asked questions

What is a direct replacement or equivalent for 54174FM?

A close functional equivalent is the SN74175N, also a TTL D flip-flop in a Bulk package. The SN74175N uses the 74-series commercial temperature range, while the 54174FM is the 54-series military/industrial grade. For a pin-compatible replacement, verify the package footprint and temperature requirements against your BOM.

Is 54174FM RoHS compliant?

No, the 54174FM is marked as RoHS non-compliant. It contains lead in the solder finish or internal construction, so it cannot be used in lead-free assembly without an exemption.
