24-SOIC footprint and board-fit
The SN64BCT25244DW comes in a 24-SOIC package with a 0.295-inch (7.50 mm) body width — the standard wide-body SOIC footprint that places cleanly on a 1.6 mm PCB with a 0.050-inch pitch. The surface-mount leads are coplanar enough for a standard reflow profile; no exotic paste or stencil required. It ships in a tube, so the pick-and-place feeder needs to handle tube-fed parts — not a reel. If your line is set up for tape-and-reel only, budget for a tube feeder or hand-place the first article.
Output drive and bus loading
This buffer delivers 80 mA source and 188 mA sink per output — enough to drive a heavily loaded data bus or a bank of LEDs without external transistors. The 3-state output lets multiple buffers share the same bus lines; the high-impedance state disconnects the output when the enable is inactive. The 2-element, 4-bit-per-element configuration gives you 8 total channels in one package — two independent 4-bit buffers.
This covers most factory-floor control cabinets, telecom shelters, and outdoor enclosures that see seasonal extremes. If your system lives inside a temperature-controlled room, this grade gives generous margin. The non-inverting logic type means the output follows the input polarity — no inversion in the signal path. That simplifies timing analysis in a synchronous bus because you don't need to account for a logic inversion at the buffer stage.
