MNSCAN18541T-X REV 1A0
MICROCIRCUIT DATA SHEET
SERIALLY CONTROLLED ACCESS NETWORK NON-INVERTING LINE
DRIVER WITH TRI-STATE OUTPUTS
General Description
The SCAN18541T is a high speed, low-power 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 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).
