The MAX921–MAX924 single, dual, and quad micro-  
p owe r, low-volta g e c omp a ra tors fe a ture the lowe s t

TTL/CMOS outputs that sink and source current.

Power Supplies:  
Single +2.5V to +11V  
Dual ±1.25V to ±5.5V  
Id e a l for 3V or 5V s ing le -s up p ly a p p lic a tions , the  
MAX921–MAX924 operate from a single +2.5V to +11V  
supply (or a ±1.25V to ±5V dual supply), and each  
c omp a ra tors inp ut volta g e ra ng e s wing s from the  
ne g a tive s up p ly ra il to within 1.3V of the p os itive  
supply.  
Input Voltage Range Includes Negative Supply  
Internal 1.182V ±1% Bandgap Reference  
Adjustable Hysteresis  
The MAX921–MAX924s uniq ue outp ut s ta g e c on-  
tinuously sources as much as 40mA. And by eliminating  
power-supply glitches that commonly occur when com-  
parators change logic states, the MAX921–MAX924  
minimize parasitic feedback, which makes them easier to  
use.  
TTL/CMOS-Compatible Outputs  
12µs Propagation Delay (10mV Overdrive)  
No Switching Crowbar Current  
40mA Continuous Source Current  
The single MAX921 and dual MAX923 provide a unique  
a nd s imp le me thod for a d d ing hys te re s is without  
feedback and complicated equations, simply by using  
the HYST pin and two resistors.
