Altera blasters missing ESD protection - Morten Leikvoll - 2010-08-19 09:45:00

Ive seen some different blasters now and they are
all missing ESD protection 
on the jtag pins. A colleague has blown quite a few now. The jtag signals 
only have a small L and then goes direct into level translators that has ESD 
warning in their datasheets. Does anyone know of a protected or opto 
isolated device within a reasonable price?

Maybe solder these on?

Maybe you want to try our EEBlaster:
http://www.entner-electronics.com/tl/index.php/eeblaster.html

Our level-translator have following specifications:
ESD Protection Exceeds JESD 22
=96 8000-V Human-Body Model
=96 150-V Machine Model
=96 1000-V Charged-Device Model
(Because of series-resistors on the PCB, it will be even higher in
real life...) We have heard of no field-failure of any EEBlaster up to
now.

Thomas
