JT 2139 TAP Isolator

The JT 2139 is a TAP signal isolation module designed for use in 'combinational' test systems that utilise multiple instrument interfaces. To avoid parasitic capicitance 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.

  • Galvanically isolates TAP signals
  • Simple compact design
  • Universally applicable
