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.

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
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.
