Digital transistor (built-in resistors)
DTA144VUA / DTA144VKA / DTA144VSA
Features
!!!!
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 device design easy.
4) Higher mounting densities can be achieved.
