Features  

1) Built-In Biasing Resistor  

ꢀ

ꢀ

2) Built-in bias resistors enable the configuration of  

ꢀ

an inverter circuit without connecting external  

ꢀ

input resistors (see inner circuit) .

3) The bias resistors consist of thin-film resistors  

ꢀ

with complete isolation to allow negative biasing  

ꢀ

of the input. They also have the advantage of  

ꢀ

completely eliminating parasitic effects.  

4) Only the on/off conditions need to be set  

ꢀ

for operation, making the circuit design eas
