KA239/KA239A,KA339/KA339A  
KA3302,KA2901  
Quad Comparator  
Features  
Description  
• Single or dual supply operation  
• Wide range of supply voltage  
The KA239/KA239A,KA339/KA339A,KA3302,KA2901  
consist of four independent voltage comparators designed  
to operate from single power supply over a wide voltage  
range.  
KA239/KA239A, KA339/KA339A, KA2901 : 2 ~ 36V  
(or ±1 ~ ±18V)  
KA3302 : 2 ~ 28V (or ±1 ~ ±14V)  
• Low supply current drain 800µA Typ.  
• Open collector outputs for wired and connectors  
• Low input bias current 25nA Typ.  
14-DIP  
• Low Input offset current ±2.3nA Typ.  
• Low input offset voltage ±1.4mV Typ.  
• Common mode input voltage range includes ground.  
• Low output saturation voltage  
1
• Output compatible with TTL. DTL and MOS logic system
