JT 2139 TAP Isolator

מאפיינים מרכזיים

The JT 2139 is a TAP signal isolation module designed for use in combinational test systems that utilise multiple instrument interfaces. To avoid parasitic capacitance effects and/or unwanted ground loops the JT 2139 can be used to completely galvanically isolate any JTAG Technologies boundary-scan controller from the remainder of the instrumentation system. JT 2139 isolators are a standard component of the JTAG Technologies ‘Symphony’ systems that integrate boundary-scan with In-Circuits Testers etc..
