General Description
The SCAN182245A is a high performance BiCMOS bidi-
rectional line driver featuring separate data inputs orga-
nized 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).
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
