MAXIM MAX900, MAX903 Technical data

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.
technical support for assistance.
General Description
The MAX900–MAX903 high-speed, low-power, single/ dual/quad voltage comparators feature differential ana­log inputs and TTL-logic outputs with active internal pull­ups. Fast propagation delay (8ns typ at 5mV overdrive) makes the MAX900–MAX903 ideal for fast A/D convert­ers 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 sup­ply 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.

ELECTRICAL CHARACTERISTICS
(VCC= +5V, VEE= -5V, VDD= +5V, LE1–LE4 = logic high, TA= +25°C, unless otherwise noted.)
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.
