Feature
1. V
CE
(sat) is lower than conventional products.
2. Built-in bias resistors enable the configuration of
an inverter circuit without connecting
external input resistors (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 device design easy.
