3 2 — — IN+ Noninverting Input
4 3 — — IN- Inverting Input
— 6 — — SHDN
Shutdown: MAX9141 is active when SHDN is driven high;
MAX9141 is in shutdown when SHDN is driven low.
— 5 — — LE
The output is latched when LE is low. The latch is transparent
when LE is high.
1 7 — — OUT Comparator Output
— 8 — — N.C. No Connection. Not internally connected.
