Inverter, Interface, Driver
zFeatures
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 negative biasing of
the input, and parasitic effects are almost completely
eliminated.
3) Only the on / off conditions need to be set
for operation, making the device design easy .
4) Higher mounting densities can be achieved.
