MAX903CSA+ Analog Devices

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. MAX900MAX903 19-2887 Rev. 5 2/05 High-Speed, Low-Power Voltage Comparators General Description Features 8ns (typ) Propagation Delay The MAX900MAX903 high-speed, low-power, single/ dual/quad voltage comparators feature differential ana- 18mW/Comparator Power Consumption (+5V, typ) log inputs and TTL-logic outputs with active internal pull- ups. Fast propagation delay (8ns typ at 5mV overdrive) Separate Analog and Digital Supplies makes the MAX900MAX903 ideal for fast A/D convert- Flexible Analog Supply: +5V to +10V or 5V ers and sampling circuits, line receivers, V/F converters, and many other data-discrimination applications. Input Range Includes Negative Supply Rail All comparators can be powered from separate analog TTL-Compatible Outputs and digital power supplies or from a single combined sup- TTL-Compatible Latch Inputs (Except MAX901) ply voltage. The analog input common-mode range includes the negative rail, allowing ground sensing when Ordering Information powered from a single supply. The MAX900MAX903 consume 18mW per comparator when powered from +5V. PART TEMP RANGE PIN-PACKAGE The MAX900MAX903 are equipped with independent MAX900ACPP 0C to +70C 20 Plastic DIP TTL-compatible latch inputs. The comparator output states are held when the latch inputs are driven low. The MAX900BCPP 0C to +70C 20 Plastic DIP MAX901 provides the same performance as the MAX900/MAX902/MAX903 with the exception of the MAX900ACWP 0C to +70C 20 Wide SO latches. MAX900BCWP 0C to +70C 20 Wide SO For newer, pin-for-pin compatible parts with the same MAX900AEPP -40C to +85C 20 Plastic DIP speed and only half the power dissipation, see the MAX9201/MAX9202/MAX9203 data sheet.
