LM6511 180 ns 3V Comparator
March 2003
LM6511
180 ns 3V Comparator
General Description
The LM6511 voltage comparator is ideal for analog-digital
interface 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
diss
<
9.45 mW at V
+
=
+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.
