LM6511

180 ns 3V Comparator

General Description

The LM6511 voltage comparator is ideal for analog-digital in-

terface circuitry when only a +3V or +3.3V supply is avail-

able. 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 (P

+2.7V and V

This voltage comparator offers many features that are avail-

able 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.
