-100mA / -50V Digital transistors
(with built-in resistors)
DTA144EB / DTA144EM / DTA144EE / DTA144EUA / DTA144EKA
Applications
Inverter, Interface, Driver
Features
1) Built-in bias resistors enable the configuration of
an inverter circuit without connecting external
input resistors (see the equivalent circuit).
2) The bias resistors consist of thin-film resistors with
complete isolation to allow positive biasing of the input.
They also have the advantage of almost completely
eliminating parasitic effects.
3) Only the on / off conditions need to be set for operation,
making the device design easy.
