D405: use Nexperia part sourced from Digi-Key direct The previously selected part was from a Digi-Key marketplace vendor, and they seem to not actually have that part, as the order has been in limbo for over a month - so I put in the time and effort to look around, and found a readily available equivalent part from Nexperia.

module inv_buffer_74LVC1G04 (GND, Vcc, A, Y);

input GND, Vcc;
input A;
output Y;

/* instantiate the package; the mapping of signals to pins is defined here */

pkg_XSON6 pkg  (.pin_1(),	/* no connect */
		.pin_2(A),
		.pin_3(GND),
		.pin_4(Y),
		.pin_5(),	/* no connect */
		.pin_6(Vcc)
	);

endmodule
