LM612  
Dual-Channel Comparator and Reference  
General Description  
Features  
COMPARATORS  
The dual-channel comparator consists of two individual  
comparators, having an input voltage range that extends  
down to the negative supply voltage Vb. The common  
open-collector output can be driven low by either half of the  
LM612. This configuration makes the LM612 ideal for use  
as a window comparator. The input stages of the compara-  
tor have lateral PNP input transistors which maintain low  
input currents for large differential input voltages and swings
