FUNCTION
1
CLEAR
Clear Input resets the latched output. With VIN > VTH, pulse CLEAR high for a minimum of 1µs to reset the
output latch. Connect to VCC to make the latch transparent.

System Supply Input
4
IN
Noninverting Input to the Comparator. The inverting input connects to the internal 1.204V bandgap reference.
5
OUT
Open-Drain (MAX834) or Push/Pull (MAX835) Latched Output. OUT is active low.
