Features
•
Built-in bias resistors enable the configuration of an inverter circuit without connecting external input
resistors (see equivalent circuit).
•
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.
•
Only the on/off conditions need to be set for operation, making device design easy.
•
Two DTC143Z chips in a SOT-363 package.
•
Mounting by SOT-323 automatic mounting machines is possible.
•
Mounting cost and area can be cut in half.
•
Transistor elements are independent, eliminating interference.
•
Complements the HBA143ZS6R.
•
Pb-free package.
