Shutdown Input. The polarity of SHDN is dependent on the
state of SHDM.
Shutdown Input. Active-low shutdown input.
Inverting Input
Shutdown-Mode Polarity Input. SHDM controls the polarity
of SHDN. Connect SHDM high for an active-high SHDN
input. Connect SHDM low for an active-low SHDN input
(see Table 1).
