GS1T70-D540 Datasheet (STMicroelectronics)

GS1T70-D540, ISDN DC-DC CONVERTER

The GS1T70-D540/2 converter has been designed for the “U” interface of an ISDN-NTBA (Network Termination Basic Access) system with either 4B3T or 2B1Q standard trasmission.

Two outputs, 5V/72mA and 40V/12mA are supplied.

The converter offers short-circuit protection (shortcircuit on 40V output doesn
