SCAN16512
Low Voltage Universal 16-bit IEEE 1149.1 Bus
Transceiver with TRI-STA TE Outputs
General DescriptionThe SCAN16512isa 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 functionis configurableasa D-type Latchor Flip-Flop,
and can operatein transparent, latched,or clocked mode.
This deviceis compliant with IEEE 1149.1 Standard Test
Access Port and Boundary Scan Architecture withthe incor-
porationof the defined boundary-scan test logic and test
access port consistingof Test Data Input (TDI), Test Data
Out (TDO), Test Mode Select (TMS), Test Clock (TCK), and
Test Reset (TRST).
Features IEEE 1149.1 (JTAG) Compliant 2.7Vto 3.6V VCC Operation TRI-STATE outputsfor bus-oriented applications Dual byte-wide datafor bus applications Power down high Impedance inputs and outputs Optional Bus Holdon data inputs eliminatesthe need
for external pullup/pulldown resistors (SCANH16512,
SCANH162512 versions) Optional 25Ω series resistorsin outputsto minimize
noise and eliminate termination resistors (SCAN162512,
SCANH162512 versions) Supports live insertion/withdrawal Includes CLAMP and HIGHZ instructions
