Product details

Device identity and functional role

The Texas Instruments 74FCT544ASC is a bus transceiver from the FCT series, designed for bidirectional data flow on a bus line with 3-state outputs. As a Logic IC in the FCT family, it provides the high-speed, low-power characteristics typical of the series, suited for bus-oriented data paths in digital systems.

Lifecycle and compliance

RoHS non-compliant designation means the part contains lead or other restricted substances above the RoHS threshold — a factor for projects requiring full RoHS conformity.

Packaging and procurement

Supplied in bulk packaging, the 74FCT544ASC is suited for through-hole assembly or prototyping where tube or tray handling is preferred over tape-and-reel.

Frequently asked questions

Is the 74FCT544ASC RoHS compliant?

No, the 74FCT544ASC is marked as RoHS non-compliant, indicating it contains lead or other restricted substances above the RoHS threshold.

How does the 74FCT544ASC compare to the SN74AHCT540DGVR?

The SN74AHCT540DGVR is a buffer/inverting logic IC from the 74AHCT series, surface-mount, with 8-bit elements and 3-state outputs, operating at 4.5 V supply. The 74FCT544ASC is a bus transceiver from the FCT series, bulk package, with different logic function and supply voltage characteristics — they are not drop-in replacements without board-level changes.
