SCAN182245A
Non-Inverting Transceiver with
25
X
Series Resistor Outputs
General Description
The SCAN182245A is a high performance BiCMOS bidirec-
tional 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 Se-
lect (TMS), and Test Clock (TCK).
