blinked. This problem was eventually solved by driving the LED with a discrete transistor instead of a free 74AC14 gate and decoupling this driver with an RC-combination.
CMOS logic gates have a totem pole output that is famous for "overlap" where both transistors on briefly turned on at the same time, resulting in large current spike from the power supply. It would be interesting to see if this was the problem, or whether it was the "antenna" connected to the output.
