LM393  
LINEAR INTEGRATED CIRCUIT  
DUAL DIFFERENTIAL  
COMPARATOR  
SOP-8  
„
DESCRIPTION  
The UTC LM393 consists of two independent voltage  
comparators, designed specifically to operate from a single power  
supply over a wide voltage range.  
TSSOP-8  
„
FEATURES  
* Single or dual supply operation.  
* Wide operating supply range  
DIP-8  
(VCC=2V ~ 36V or ±1 ~ ±18V)  
* Input common-mode voltage includes ground.  
* Low supply current drain ICC=0.8mA (Typical).  
* Low input bias current IBIAS=25nA (Typical).  
* Output compatible with TTL, DTL, and CMOS logic system.  
*Pb-free plating product number: LM393L
