Quad RS-422/485 line driver in a Bulk-packaged DIP
The DS36954VX/NOPB is a quad line transceiver from Texas Instruments, integrating four independent transceiver functions each with a single driver — a 4-func, 1-driver architecture per the device description. It ships in Bulk format, which means loose tubes or trays rather than tape-and-reel — a detail that matters for prototype runs or low-volume builds where you don't want to buy a full reel.
Not a drop-in for CAN transceivers
The SN65HVD233MDREP is a CANbus transceiver (half-duplex, 1 Mbps) — a different protocol and pinout than the RS-422/485 family the DS36954VX/NOPB belongs to. These are not cross-compatible without a board spin.
