5.1 Application – JTAG

A voltage level translator is necessary while interfacing numerous sub-systems that operate at different voltage levels. In enterprise computing applications, JTAG interface can be found in Campus and Branch Switches as shown in Figure 5-2. The JTAG port enables easier debugging during periodic maintenance of the server.
