25ns, Dual/Quad/Single, Low-Power,
TTL Comparators
General Description
The MAX9107/MAX9108/MAX9109 dual/quad/single,
high-speed, low-power voltage comparators are designed
for use in systems powered from a single +5V supply.
Their 25ns propagation delay (with 10mV input overdrive)
is achieved with a power consumption of only 1.75mW
per comparator. The wide input common-mode range
extends from 200mV below ground to within 1.5V of the
positive supply rail.
The MAX9107/MAX9108/MAX9109 outputs are TTL-
compatible, requiring no external pullup circuitry. These
easy-to-use comparators incorporate internal hysteresis
to ensure clean output switching even when the devices
are driven by a slow-moving input signal.
The MAX9107/MAX9108/MAX9109 are higher-speed,
lower-power, lower-cost upgrades to industry-standard
comparators MAX907/MAX908/MAX909. The MAX9109
features an output latch but does not have complemen-
tary outputs.
The dual MAX9107 is available in both 8-pin SO and
SOT23 packages. The quad MAX9108 is available
in 14-pin TSSOP and SO packages while the single
MAX9109 is available in an ultra-small 6-pin SC70 pack-
age, a space-saving 6-pin SOT23 package and an 8-pin
SO package.
