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 VCC(A). To provide VESA I2C-compatible signals 3.3 V should be

applied to VCC(A). If voltage translation is not required VCC(A) should be connected to

VCC(B). Switch terminals include integrated pull-up resistors; inputs (SDA0, SCL0) are

pulled up to VCC(A), outputs (SDA1, SCL1 and SDA2, SCL2) are pulled up to VCC(B). When

the NX5DV715 is disabled (EN = LOW), the pull-up resistors are also disabled.

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.
