Additional output circuit for differential signal transmission during boundary scan

摘要

The circuit detects an interruption in differential signal conductors to which a driver (AT1) is connected, whereby the driver can be switched in a high impedance manner and two output drivers (ZAT1,2) are provided whose outputs can be connected to separate differential signal sources and each of which can be switched in a high impedance manner.. AN Independent claim is also included for the following: an output circuit for differential data transmission with a line connection to a terminating potential.
