Altera blasters missing ESD protection

[Morten Leikvoll]

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
– 8000-V Human-Body Model
– 150-V Machine Model
– 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.
