The '54' prefix indicates the military temperature range (-55 to +125 °C), making it suitable for avionics, defense, and other extended-environment backplanes where commercial or industrial parts would not hold up. It is an 8-bit D-type flip-flop with 3-state outputs — the bus driver function means it isolates the data source from the bus until the output-enable line is asserted, preventing bus contention in multi-drop configurations. ## Active production, legacy tin/lead finish RoHS non-compliant — the part uses tin/lead solder finish, which is the expected termination for a '54' series device. This is an advantage for mil/aero assemblies that require leaded solder per MIL-STD-2000 or NASA-STD-8739; it is a blocker for RoHS-mandated commercial builds unless an exemption applies. ## Sourcing and cross-reference considerations The difference is the logic family: ALS (Advanced Low-Power Schottky) vs LVT (Low-Voltage Technology). LVT typically runs at 3.3 V with 5 V-tolerant inputs; ALS is a 5 V-only family. If the board is 5 V-powered and the timing margin is comfortable, the ALS variant is a direct drop-in. If the design uses 3.3 V rails, the LVT part is the correct choice. Sourced per RFQ through independent distribution — no stock-holding claim, but the part is actively produced and available through authorized TI channels.","metaTitle":"SNJ54LVT574FK Texas Instruments 8-bit Bus Driver, Active","metaDescription":"SNJ54LVT574FK 8-bit bus driver from TI, LVT series, active production, RoHS non-compliant.

Electrically, the LVT family runs at 3.3 V with 5 V-tolerant inputs, while the ALS family is 5 V-only. If the board supplies 5 V to the Vcc pin, the LVT part may be overstressed.
