DESCRIPTION
The LM6511 voltage comparator is ideal for analog-
digital interface circuitry when only a +3V or +3.3V
supply is available. The open-collector output permits
signal compatibility with a wide variety of digital
families: +5V CMOS, +3V CMOS, TTL and so on.
Supply voltage may range from 2.7V to 36V between
supply voltage leads. The LM6511 operates with little
power consumption (Pdiss < 9.45 mW at V+ = +2.7V and V− = 0V).
This voltage comparator offers many features that are
available in traditional sub-microsecond comparators:
output sync strobe, inputs and output may be isolated
from system ground, and wire-ORing. Also, the
LM6511 uses the industry-standard, single
comparator pinout configuration.
