DTA144EC3

CYStek Product Specification

DTA144EC3

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.

• Complements the DTC144EC3

• Pb-free package
