ZD
ESD-Zener diode: 6.1 V typ., max 5 mA;
RST(ON) < 380 Ω at 1.6 mA, ESD zener diodes are not
to be used as voltage clamp at DC conditions.
Operation in this mode may result in a drift of the zener
voltage (increase of up to 1 V).

Any kind of load. In case of Input=high is VOUT ≈ VIN - VIN(T+) .
Due to VGND >0, no VST = low signal available.
