Description
40ns, Low-power, 3v/5v, Rail-to-rail Single-supply Comparators
Manufacturer
Maxim Integrated Products, Inc.
Datasheet
The MAX9140/MAX9141 are single and the MAX9142/
MAX9144 are dual/quad high-speed comparators opti-
mized for systems powered from a 3V or 5V supply. The
MAX9141 features latch enable and device shutdown.
These devices combine high speed, low power, and
rail-to-rail inputs. Propagation delay is 40ns, while sup-
ply current is only 150µA per comparator.
The input common-mode range of the MAX9140/
MAX9141/MAX9142/MAX9144 extends beyond both
power-supply rails. The outputs pull to within 0.3V of
either supply rail without external pullup circuitry, mak-
ing these devices ideal for interface with both CMOS
and TTL logic. All input and output pins can tolerate a
continuous short-circuit fault condition to either rail.
Internal hysteresis ensures clean output switching, even
with slow-moving input signals.
The MAX9140/MAX9141/MAX9142/MAX9144 are high-
er-speed, lower-power, and lower-cost upgrades to
industry-standard comparators MAX941/MAX942/
MAX944.
The MAX9140 are offered in tiny 5-pin SC70 and SOT23
packages. The MAX9141 and MAX9142 are available in
8-pin SOT23 and SO packages, while the MAX9144 is
available in both 14-pin SO and TSSOP packages.
