MAX909 datasheet

Single/Dual/Quad High-Speed, Ultra Low-Power,
Single-Supply TTL Comparators
_______________General Description
The MAX907/MAX908/MAX909 dual, quad, and single
high-speed, ultra low-power voltage comparators are
designed for use in systems powered from a single
+5V supply; the MAX909 also accepts dual ±5V sup-
plies. Their 40ns propagation delay (with 5mV input
overdrive) is achieved with a power consumption of
only 3.5mW per comparator. The wide input common-
mode range extends from 200mV below ground (below
the negative supply rail for the MAX909) to within 1.5V
of the positive supply rail.
Because they are micropower, high-speed compara-
tors that operate from a single +5V supply and include
built-in hysteresis, these devices replace a variety of
older comparators in a wide range of applications.
MAX907/MAX908/MAX909 outputs are TTL compati-
ble, requiring no external pull-up circuitry. All inputs
and outputs can be continuously shorted to either sup-
ply rail without damage. These easy-to-use compara-
tors incorporate internal hysteresis to ensure clean out-
put switching even when the devices are driven by a
slow-moving input signal.
The MAX909 features complementary outputs and an
output latch. A separate supply pin for extending the
analog input range down to -5V is also provided.
The dual MAX907 and single MAX909 are available in
8-pin DIP and small-outline packages, and the quad
MAX908 is available in 14-pin DIP and small-outline
packages. These comparators are ideal for single
+5V-supply applications that require the combination
of high speed, precision, and ultra-low power
dissipation.

Stresses beyond those listed under “Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
