8-bit bus driver in LVT logic family
The SNJ54LVT573FK is an 8-bit bus driver from Texas Instruments' LVT series, designed for high-speed interface and transceiver applications in military/aerospace-grade systems.
RoHS compliance and sourcing posture
Marked RoHS non-compliant, this part contains lead and is exempt under certain military/aerospace exemptions — verify your end-market regulatory requirements before committing the BOM line. Supplied in bulk package form — loose parts, not tape-and-reel — which suits low-volume prototype runs or manual assembly lines but may require re-taping for automated pick-and-place.
How does SNJ54LVT573FK compare to SNJ54ALS574AFK?
Both parts are 8-bit bus-interface devices in the same package form (Bulk), but the LVT573 uses LVT (Low-Voltage Technology) logic while the ALS574 uses ALS (Advanced Low-Power Schottky) — the LVT variant operates at lower supply voltages and typically offers faster propagation delays, but the ALS574 may be preferred in legacy 5 V-only systems where LVT's 3.3 V core requires a level translator. Pinout and footprint are not guaranteed identical — confirm the board layout against the datasheet before substituting one for the other.
