1) Built-in bias resistors enable the configuration of
an inverter circuit without connecting external
input resistors.
2) The bias resistors consist of thin-film resistors
with complete isolation to allow positive biasing of
the input, and parasitic effects are almost

3) Only the on / off conditions need to be set for
operation, making the device design easy .
4) Higher mounting densities can be achieved.
