General Description

The MAX900–MAX903 high-speed, low-power, single/

dual/quad voltage comparators feature differential ana-

log inputs and TTL-logic outputs with active internal pull-

ups. Fast propagation delay (8ns typ at 5mV overdrive)

makes the MAX900–MAX903 ideal for fast A/D convert-

ers and sampling circuits, line receivers, V/F converters,

and many other data-discrimination applications.

All comparators can be powered from separate analog

and digital power supplies or from a single combined sup-

ply voltage. The analog input common-mode range

includes the negative rail, allowing ground sensing when

powered from a single supply. The MAX900–MAX903

consume 18mW per comparator when powered from +5V.

The MAX900–MAX903 are equipped with independent

TTL-compatible latch inputs. The comparator output

states are held when the latch inputs are driven low. The

MAX901 provides the same performance as the

MAX900/MAX902/MAX903 with the exception of the

latches.

For newer, pin-for-pin compatible parts with the same

speed and only half the power dissipation, see the

MAX9201/MAX9202/MAX9203 data sheet.
