l Features
1)Built-in bias resistors enable the configuration
of an inverter circuit without connecting
external input resistors.(see equivalent circuit)
2)The bias resistors consist of thin-film resistors
with complete isolation to allow negative
biasing of the input. They also have the advantage
of almost completely eliminating parasitic effects.
3)Only the on/off conditions need to be set for
operation, making the device desigh easy.
