The MAX971–MAX974 and MAX981–MAX984 single/  
dual/quad low-voltage comparators feature the lowest

MAX974) or ±2% (MAX981–MAX984) voltage reference  
and programmable hysteresis.

(MAX9_1/MAX9_2/MAX9_3)  
Ultra-Low 4µA Max Quiescent Current  
Over Extended Temp. Range (MAX971/MAX981)  
Power Supplies: Single +2.5V to +11V  
Dual ±1.25V to ±5.5V  
Input Voltage Range Includes Negative Supply  
Internal 1.182V ±1% Bandgap Reference  
Ideal for 3V or 5V single-supply applications, these  
devices operate from a single +2.5V to +11V supply (or  
±1.25V to ±5.5V dual supplies), and each comparators  
input voltage ranges from the negative supply rail to within  
1.3V of the positive supply.  
12µs Propagation Delay (10mV Overdrive)  
Output Has Separate GND Pin (MAX9_1/MAX9_4)  
The single MAX971 and MAX981 and the dual MAX973  
and MAX982/MAX983 provide a unique, simple method  
for adding hysteresis without feedback or complicated  
e q ua tions , s imp ly b y us ing the HYST p in p lus two

Oscillator Circuits  
The MAX971–MAX974 and MAX981–MAX984s open-  
drain outputs permit wire-ORed configurations. Thanks to  
an 11V output range and separate GND pin for the output  
transistor (MAX971/MAX974, MAX981/MAX984), these  
devices are ideal for level translators and bipolar to single-  
ended converters. For similar devices with complementary  
output stages, see the MAX921–MAX924 (1% reference)  
and the MAX931–MAX934 (2% reference).
