The Texas Instruments SN74LVCH245DBLE is a bus transceiver, a logic-level bidirectional interface that sits between two data buses, typically on a board that needs to pass signals between different voltage domains or drive a shared bus without contention. It is part of the LVC family, which offers 5 V tolerant inputs and outputs even when running from a 3.3 V supply — useful in mixed-voltage designs where legacy 5 V logic meets a lower-voltage controller.
RoHS status — a BOM-line gate
This part is RoHS non-compliant. If your BOM requires RoHS 10 or any lead-free exemption, the SN74LVCH245DBLE will not pass a compliance audit. That matters most for EU-market products, medical devices, or any assembly going through a lead-free reflow profile. For legacy or military/aerospace builds that still use tin-lead solder, the non-compliant status is irrelevant — and the part is often easier to source in this form because it avoids the premium on RoHS-converted logic.
For a high-volume pick-and-place line, that means extra handling: the parts need to be loaded into a feeder or hand-placed. For a rework bench or a low-volume prototype run, Bulk is actually easier — no reel to unspool, no moisture-bake cycle if the bag seal is intact. Store the tubes in a dry cabinet or resealable bag with desiccant; the LVC family is not especially moisture-sensitive, but Bulk parts lack the sealed reel bag that protects tape-and-reel inventory.
