SCAN182541A
Non-Inverting Line Driver
with 25Ω 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).
Features
s IEEE 1149.1 (JTAG) Compliant
s High performance BiCMOS technology
s 25Ω series resistor outputs eliminate need for external
terminating resistors
s Dual output enable signals per byte
s 3-STATE outputs for bus-oriented applications
s 25 mil pitch SSOP (Shrink Small Outline Package)
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
