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.
