Detailed Description
The MAX4814E provides routing for low-frequency
DVI/HDMI signals. The MAX4814E is a bidirectional 2:4
DVI/HDMI switch. Each switch consists of five single-
pole/single-throw (SPST) channels. The channels have a
low 3
Ω
(typ) on-resistance to route +5V and drain, and
three channels to route data. Channels A0, A4, B0, B4,
SW_0, and SW_4 have a 3
Ω
(typ) on-resistance to route
+5V and drain, and the remaining channels A1–A3,
B1–B3, SL0_3, and SW_1 have a 12
Ω
(typ) on-resis-
tance to route data. The device features a mode input to
control the device using direct-control logic inputs or an
I
2
C interface. Connect MODE to GND to control the
device using the direct-control bits. Connect MODE to
V
DD
to control the device using I
2
C. In I
2
C mode, the
MAX4814E controls the MAX3845 (see Figure 5).
Analog Signal Levels
Signal inputs over the full voltage range (0V to V
DD
) are
passed through the switch with minimal change in on-
resistance (see the Typical Operating Characteristics).
The switches are bidirectional. Therefore, switch A_,
switch B_, and switch SW_ can be either inputs or outputs.
Switch Control
The MAX4814E features a mode input to control the
device through either an I
2
C interface or through direct-
control logic inputs. Connect MODE to GND (mode 0) to
control the device using the direct-control inputs DA_ and
DB_ (see Table 1 and Figure 6). Connect MODE to V
DD
(mode 1) to control the device using the I
2
C interface.
Direct Control Method (Mode 0)
In mode 0, DA0/DO0 becomes input DA0, DA1/DO1

Direct-Control Bit I/O. In mode 0, DA0/DO0 is set as an input, DA0, to control switch
connections. In mode 1, DA0/DO0 is set as an output, DO0. The output bits are used to
drive the MAX3845.
Direct-Control Bit I/O. In mode 0, DA1/DO1 is set as an input, DA1, to control switch
connections. In mode 1, DA1/DO1 is set as an output, DO1. The output bits are used to
drive the MAX3845.
Direct-Control Bit I/O. In mode 0 DA2/DO2 is set as an input, DA2, to control switch
connections. In mode 1, DA1/DO1 is set as an output, DO2. The output bits are used to
drive the MAX3845.
Direct-Control Bit I/O. In mode 0 DB0/DO3 is set as an input, DB0, to control switch
connections. In mode 1, DB0/DO3 is set as an output, DO3. The output bits are used to
drive the MAX3845.
Direct-Control Bit I/O. In mode 0, DB1 is set as an input. In mode 1, DB1 is high
impedance.
