Six-bit buffer with 3-state outputs — what it buys the repair bench
The 74HCT365D/C4118 is a single-element, six-bit non-inverting buffer from the 74HCT series, with 3-state outputs that let you disconnect the bus when the output-enable pin is pulled high. The 16-SOIC package is a common footprint — easy to probe, easy to swap.
Why the temperature range matters for a board autopsy
When I see a scorch mark near a buffer on a motor-drive controller, the first thing I check is whether the replacement part can handle the same ambient. This one is rated -40°C to 125°C, which covers most industrial and automotive environments. The 6 mA sink and source capability per output is enough to drive a few CMOS inputs or a short cable stub — don't expect it to light a relay coil, but for signal buffering it's fine.
Lifecycle — no LTB scramble
That means no last-time-buy clock ticking, no panic buys.
