Circuit Description (continued)

Driver Output Protection

The Edge211 is designed to operate in a functional testing

environment where a controlled impedance (typically 50

Ohms) is maintained between the pin electronics and the

DUT. In general, there will be an external resistor at the

driver output which series terminates the transmission line

to the DUT. In this environment, the driver can withstand

a short to any legal DUT voltage for an indefinite amount

of time.

In a low impedance application with no additional output

series resistance, care must be exercised and systems

should be designed to check for this condition and tristate

the driver if a short is detected.

The driver does NOT have on-chip short circuit protection

or limitation circuitry.
