Sorry about the new thread and line spacing.
PXA255 JTAG is not 5V tolerant. The Intel datasheet indicates VCCCQ+0.3 or 4V max.
This looks clamped to me. The spec also indicates max input current of 5mA so if
You have a series resistor to limit the current, you may be ok. The circuit which uses
a 74HC244 should operate from 2V - 6V so those concerned with 5V toterance should
just power it from 3.3V.
