SCAN18373T
Transparent Latch with 3-STATE Outputs
General Description
The SCAN18373T is a high speed, low-power transparent
latch featuring separate data inputs organized into dual 9-
bit bytes with byte-oriented latch enable and output enable
control signals. This device is compliant with IEEE 1149.1
Standard Test Access Port and Boundary Scan Architec-
ture 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).
