74HC hex buffer with 3-state — the part that saves you from a second level shifter
The CD74HC365M96 is a 74HC-series hex non-inverting buffer with 3-state outputs, in a 16-SOIC package. It runs on a 2V to 6V supply, so you can hang it directly on a 5V bus without a separate level translator — the 7.8mA source and sink per channel is enough to drive a handful of CMOS inputs or a short ribbon cable. The full military temperature range (–55°C to 125°C) means it's at home in an engine bay, a satellite payload, or a lab oven, not just a desk fan.
7.8mA output drive — enough for a bus, not a relay
Each of the six channels can source or sink 7.8mA. That's plenty for driving the input of another HC gate, an LED with a series resistor, or a short trace on a PCB. If you need to drive a heavier load — say a 50mA relay coil or a long cable — you'll want a discrete transistor or a dedicated line driver after this buffer. The 3-state outputs let you share a data bus between multiple devices: pull the output-enable pin high and the outputs go high-impedance, so another buffer can take over the line without contention.
2V to 6V supply — 5V tolerant, no translator needed
The wide supply range covers 3.3V and 5V logic families. At 5V the HC logic levels are directly compatible with TTL and LVCMOS inputs. The 16-SOIC body (0.154" wide, 3.90mm) is a standard footprint — easy to hand-solder with a fine tip or reflow in a toaster oven. The Tape & Reel option (cut tape available) means you can order a handful for a prototype or a reel for production without changing the part number.
Active lifecycle, no LTB pressure
The CD74HC365M96 is listed as Active with ROHS3 compliance. There is no last-time-buy notice or obsolescence risk on this line. For a production BOM that needs a reliable 5V-tolerant bus buffer, this part is a safe long-term choice — no need to qualify a second source today, though the 74HC family has broad cross-vendor compatibility if you ever want one.
