74HC logic buffer with 3-state — what it does on the board
The Texas Instruments SN74HC367PWR is a non-inverting buffer from the 74HC family, packing two buffer elements with independent 3-state output enables — one element handles 2 bits, the other handles 4 bits, giving you a 6-bit buffer total in a single 16-TSSOP package. It runs on a 2V to 6V supply rail, which makes it a natural fit for mixed-voltage 3.3V and 5V logic systems where you need to isolate a bus, drive a longer trace, or gate a data line without inverting the signal. The 3-state outputs let you float the bus when the enable is deasserted, so multiple buffers can share a line without contention.
7.8 mA output drive — enough for what?
Each output sources or sinks 7.8 mA. That drives a handful of TTL or HC inputs, clocks a small capacitive load on a short trace, or lights a low-current LED with a series resistor.
Active and ROHS3 — no lifecycle surprises
The 74HC series has been around for decades and TI shows no sign of winding it down.
