MAX9109EUT-T

25ns, Dual/Quad/Single, Low-Power, TTL Comparators

Maxim Integrated 

MAX9107/MAX9108/MAX9109

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.
