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.
