6-bit true-output bus driver — CD4000B family
The Texas Instruments 40097BDC is a 6-bit bus driver with true (non-inverting) outputs, part of the CD4000B series of CMOS logic devices. Rated as a bus driver, it buffers six parallel data lines with enough drive to fan out to multiple loads on a backplane or peripheral bus — the true output means the data polarity matches the input, so no inversion correction needed in the downstream logic.
Package and board-fit reality
Supplied in Bulk — this is a through-hole package, not surface-mount. The 40097BDC drops into a DIP footprint on legacy or rework boards where a socket or wave-solder process is already qualified. Because it's Bulk, not tape-and-reel, pick-and-place lines need a tube feeder or manual insertion — factor that into the assembly BOM setup if your line is SMT-only.
Compliance flag — RoHS non-compliant
The 40097BDC carries a RoHS non-compliant status. This is a lead-bearing part — exempt from the 2011/65/EU directive only if the end-equipment falls under a military, aerospace, or medical exemption. For a commercial or consumer BOM, this part triggers a full REACH / RoHS review and may require a waiver or alternative sourcing. If your compliance officer needs a Pb-free alternative, the 40097BDC is not it; look at the 74HCT or 74AHCT series equivalents that are RoHS-compliant and pin-compatible in most cases.
Sourcing posture — active, no LTB window
Lifecycle status is Active — Texas Instruments has not issued a Product Change Notice (PCN) or Last-Time-Buy (LTB) notification for this part. It remains in the current catalog and is available through authorized distribution channels.
