What the DS90C363MTD is and what it does
The DS90C363MTD is a line driver from Texas Instruments, configured with three driver functions in a single package.
Housed in a 48-TFSOP package with a 0.240" body width and 6.10mm width, it is a fine-pitch surface-mount device that requires careful soldering — a hot-air station or reflow oven, not a hand iron. The supplier device package is listed as 48-TSSOP, which is the same footprint family; the two designations are often used interchangeably for this package outline. It is supplied in bulk, so expect tubes or trays rather than tape-and-reel — plan your pick-and-place setup accordingly.
Sourcing and compliance reality
The DS90C363MTD is RoHS non-compliant, which limits its use in markets with strict RoHS enforcement unless an exemption applies.
