SCAN182245A
Non-Inverting Transceiver
with 25
Series Resistor Outputs
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).
Features
s High performance BiCMOS technology
s 25
series resistors in outputs eliminate the need for
external terminating resistors
s Dual output enable control signals
s 3-STATE outputs for bus-oriented applications
s 25 mil pitch SSOP (Shrink Small Outline Package)
s IEEE 1149.1 (JTAG) Compliant
s Includes CLAMP, IDCODE and HIGHZ instructions
s Additional instructions SAMPLE-IN, SAMPLE-OUT and
EXTEST-OUT
s Power Up 3-STATE for hot insert
s Member of Fairchild’s SCAN Products
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
