NPN Silicon Surface Mount Transistor
with Monolithic Bias Resistor Network
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.
