General Description
The SCAN18245T is a high speed, low-power bidirectional
line driver featuring separate data inputs organized into dual
9-bit bytes with byte-oriented output enable and direction
control signals. This device is compliant with IEEE 1149.1
Standard 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).
