Function
TDO
Output
B7
The Test Data Output (TDO) signal carries test data out
of the S/UNI-JET via the IEEE P1149.1 test access port.
TDO is updated on the falling edge of TCK. TDO is a tri-
state output which is inactive except when scanning of
data is in progress.
TRSTB
BIAS
Input
A6
The Active low Test Reset (TRSTB) signal provides an
asynchronous S/UNI-JET test access port reset via the
IEEE P1149.1 test access port. TRSTB is a Schmitt
triggered input with an integral pull up resistor. TRSTB
must be asserted during the power up sequence.
Note: If not used, TRSTB must be connected to the
RSTB input.
Input
H20

D4
When tied to +5V, the +5V Bias (BIAS) input is used to
bias the wells in the input and I/O pads so that the pads
can tolerate 5V on their inputs without forward biasing
internal ESD protection devices. When tied to VDD, the
inputs and bi-directional inputs will only tolerate input
levels up to VDD.
