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.
2
GND System Ground
3
VCC 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.
