NX5DV4885E
Dual supply 1-of-2 VGA switch
Rev. 2 — 4 November 2011
Product data sheet
1. General description
The NX5DV4885E is a dual supply 1-to-2 VGA switch. It integrates high-bandwidth SPDT
switches with level translating switches and level translating buffers to provide switching
of input RGB signals and switching and level translation of input DDC signals to either of
two output channels as well as level translation of input H-sync and V-sync signals
The NX5DV4885E is characterized for operation from 40 C to +85 C.
2. Features and benefits
RGB switches:
Low ON resistance (4 typical)
Low ON capacitance (12 pF typical)
Low output skew (50 ps)
Low power consumption (< 2 A)
Level translation of sync and DDC signals
Over-voltage tolerant inputs
ESD protection:
HBM JESD22-A114F Class 3A exceeds 4 kV
MM JESD22-A115-A exceeds 200 V
CDM JESD22-C101D exceeds 1000 V
IEC61000-4-2 contact discharge exceeds 4 kV for I/Os
Latch-up performance exceeds 100 mA per JESD78 Class II Level A
Specified from 40 C to +85 C
3. Applications
Notebook Computers
Docking stations
Digital projectors
Computer monitors
Servers

8.3 Display-Data Channel Multiplexer
The NX5DV4885E provides two identical SPDT active-level translating switches to route
DDC signals (See Table 6). The switch outputs are limited to a diode drop below 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).

H = HIGH voltage level; L = LOW voltage level; X = Don’t care.
