AD667  
Right-justified data can be similarly accommodated. The over-  
lapping of data lines is reversed, and the address connections  
are slightly different. The AD667 still occupies two adjacent  
locations in the processor’s memory map. In the circuit of Fig-  
ure 9, location X01 loads the 8 LSBs and location X10 loads  
the 4 MSBs and updates the output.  
low, and the latch is enabled by CS going low. The AD667 thus  
occupies a single memory location.  
This configuration uses the first and second rank registers  
simultaneously. The CS input can be driven from an active-low  
decoded address. It should be noted that any data bus activity  
during the period when CS is low will cause activity at the  
AD667 output. If data is not guaranteed stable during this  
period, the second rank register can be used to provide double  
buffering.

USING THE AD667 WITH 12- AND 16-BIT BUSES  
The AD667 is easily interfaced to 12- and 16-bit data buses. In  
this operation, all four address lines (A0 through A3) are tied
