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 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..

תיאור מוצר

Features

Galvanically isolates TAP signals
Simple compact design
Universally applicable

Benefits

Small design fits easily inside test fixtures
One per TAP – only install the number you need per application
Basic 5V power supply
Full relay isolation per TAP signal

Applications

Use in ATEs to fully isolate JTAG/boundary-scan TAP signals from the remainder of the test system. Use of TAP isolation modules avoids the potential for poor functional test measurements due to stray [test] system impedances.
