MAX976/MAX978/MAX998  
Single/Dual/Quad, SOT23, Single-Supply,  
High-Speed, Low-Power Comparators  
________________General Description  
____________________________Features  
o Single-Supply Operation Down to 2.7V  
o 20ns Propagation Delay  
o 225µA Supply Current  
o 1nA Shutdown Supply Current  
o Rail-to-Rail Outputs  
The MAX976/MAX978/MAX998 dual/quad/single, high-  
speed, low-power comparators are optimized for  
+3V/+5V single-supply applications. They achieve a  
20ns propagation delay while consuming only 225µA  
supply current per comparator. The MAX998 features a  
low-power shutdown mode that places the output in a  
high-impedance state and reduces supply current  
to 1nA.  
o Ground-Sensing Inputs  
o Internal Hysteresis Ensures Clean Switching  
The MAX976/MAX978/MAX998 inputs have a common-  
mode voltage range that extends 200mV below ground.  
Their outputs are capable of rail-to-rail operation with-  
out external pullup circuitry, making these devices ideal  
for interface with CMOS/TTL logic. All inputs and out-  
puts can tolerate a continuous short-circuit fault condi-  
tion to either rail. The comparators’ internal hysteresis  
ensures clean output switching, even with slow-moving  
input signals.  
o Available in Space-Saving Packages  
SOT23 (MAX998)  
µMAX (MAX976)  
QSOP (MAX978)  
_______________Ordering Information  
For space-critical applications, the single MAX998 is  
available in a 6-pin SOT23 package, the dual MAX976  
is available in an 8-pin µMAX® package, and the quad  
MAX978 is available in a 16-pin QSOP package.
