Series Resistor Outputs
General Description
The SCAN182541A is a high performance BiCMOS line
driver featuring separate data inputs organized into dual 9-
bit bytes with byte-oriented paired output enable control
signals. This device is compliant with IEEE 1149.1 Stan-
dard Test Access Port and Boundary-Scan architecture
with the incorporation of the defined Boundary-Scan test
logic and test access port consisting of Test Data Input
(TDI), Test Data Out (TDO), Test Mode Select (TMS), and
Test Clock (TCK).
