zFeature

CE (sat) is lower than conventional product s.

1) V

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

3) 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.

4) Only the on / off conditions need to be set for operation,
making the device design ea sy.
