SCAN16512
Low Voltage Universal 16-bit IEEE 1149.1 Bus
Transceiver with TRI-STATE Outputs
General Description
The SCAN16512 is a high speed, low-power universal bus
transceiver featuring data inputs organized into two 8-bit
bytes with output enable and latch enable control signals.
This function is configurable as a D-type Latch or Flip-Flop,
and can operate in transparent, latched, or clocked mode.
This device is compliant with IEEE 1149.1 Standard Test
Access Port and Boundary Scan Architecture with the incor-
poration 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), Test Clock (TCK), and
Test Reset (TRST).
