NX5DV715
Dual supply 1-of-2 VGA switch
7.3 Display-Data Channel Multiplexer
The NX5DV715 provides two identical SPDT active-level translating switches to route
DDC signals (See Table 5
). The switch outputs are limited to a diode drop less than the
voltage applied on V
CC(A)
. To provide VESA I
2
C-compatible signals 3.3 V should be
applied to V
CC(A)
. If voltage translation is not required V
CC(A)
should be connected to
V
CC(B)
. Switch terminals include integrated pull-up resistors; inputs (SDA0, SCL0) are
pulled up to V
CC(A)
, outputs (SDA1, SCL1 and SDA2, SCL2) are pulled up to V
CC(B)
. When
the NX5DV715 is disabled (EN = LOW), the pull-up resistors are also disabled.
8. Limiting values
[1] The minimum input voltage rating may be exceeded if the input current rating is observed.
[2] For HWQFN32 package: above 137 C the value of P
tot
derates linearly with 20.5 mW/K.

Table 6. Limiting values
In accordance with the Absolute Maximum Rating System (IEC 60134). Voltages are referenced to GND (ground = 0 V).
