FEATURES
z Built-in bias resistor enable the configuration
of an inverter circuit without connecting
external input resistors.
Lead-free
z 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.
z Only the on/off conditions need to be set for operation, SOT-23
making device design easy.
APPLICATIONS
z The PNP style digital transistor.
