Application Notes
(Continued)
An alternate approach would be to tie the outputs directly
together and let all devices share a common back termina-
tion resistor in order to alleviate the gain error issue above.
The drawback in this case is the increased capacitive load
presented to the output of each LMH6572 due to the off-
state capacitance of the LMH6572.
EXPANDING THE MUX
It is possible to build higher density MUX’s by paralleling
several LMH6572’s.
Figure 4
shows a 4:1 RGB MUX using
two LMH6572’s:
If it is important in the end application to make sure that no
two inputs are presented to the output at the same time, an
optional delay block can be added, prior to the ENABLE (EN)
pin of each device, as shown.
Figure 5
shows one possible
approach to this delay circuit. The delay circuit shown will
delay ENABLE’s H to L transitions (R
1
and C
1
decay) but
won’t delay its L to H transition.
