zFeature

CE(sat) is lower than conventional products.

1) V

2) Built-in bias resistors enable the co nfiguration of an
inverter circuit without connecting external input
resistors (see equivalent circuit).

3) The bias resistors consist of t hin-film resistors with
complete isolation to allow negative biasing of the
input. They also have the advantage of almost
completely eliminating parasitic effects.

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

operation, making the devi ce design easy.
