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).
