zApplications 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 positive 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 ca.n be achieved.
z We declare that the material of product compliance with RoHS requirements.
