MAX901BESE+T

P1-P3P4-P6P7-P9P10-P12P13-P13
Not Recommended for New Designs
The MAX900 was manufactured for Maxim by an outside wafer
foundry using a process that is no longer available. It is not
recommended for new designs. A Maxim replacement or an industry
second-source may be available. The data sheet remains available for
existing users. The other parts on the following data sheet are not
affected.
For further information, please see the QuickView data sheet for this
part or contact
technical support for assistance.
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.
