MAX9201/MAX9202/MAX9203 19-1936 Rev 1 1/05 Low-Cost, 7ns, Low-Power Voltage Comparators General Description Features The MAX9201/MAX9202/MAX9203 high-speed, low- Fast 7ns Propagation Delay power, quad/dual/single comparators feature TTL logic Low 9mW/Comparator Power Consumption outputs with active internal pullups. Fast propagation delay (7ns typ at 5mV overdrive) makes these devices Separate Analog and Digital Supplies ideal for fast A/D converters and sampling circuits, line Flexible Analog Supply: +5V to +10V or 5V receivers, V/F converters, and many other data-discrim- ination, signal restoration applications. Input Voltage Range Includes All comparators can be powered from separate analog Negative Supply Rail and digital power supplies or from a single combined TTL-Compatible Outputs supply voltage. The analog input common-mode range includes the negative rail, allowing ground sensing TTL-Compatible Latch Inputs when powered from a single supply. The MAX9201/ (MAX9202/MAX9203) MAX9202/MAX9203 consume only 9mW per compara- Available in Space-Saving Packages tor when powered from a +5V supply. 8-Pin SOT23 (MAX9203) The MAX9202/MAX9203 feature output latches with TTL 14-Pin TSSOP (MAX9202) compatible inputs. The comparator output states are 16-Pin TSSOP (MAX9201) held when the latch inputs are driven low. The MAX9201 provides all the same features as the MAX9202/MAX9203 with the exception of the latches. The MAX9201/MAX9202/MAX9203 are lower power and lower cost upgrades to the MAX901/MAX902/MAX903 Ordering Information offering a 50% power savings and smaller packaging.
