NAME
FUNCTION
1 C2 — — — SHDN
Shutdown Input. The polarity of SHDN is dependent on the
state of SHDM.
——9B311SHDN
Shutdown Input. Active-low shutdown input.
2 C1 — — — IN-
Inverting Input
3 B2 — — — SHDM
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
