MAX4814E
DVI/HDMI 2:4 Low-Frequency Fanout Switch

_______________________________________________________________________________________
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 3Ω (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 3Ω (typ) on-resistance to route
+5V and drain, and the remaining channels A1–A3,
B1–B3, SL0_3, and SW_1 have a 12Ω (typ) on-resis-
tance to route data. The device features a mode input to
control the device using direct-control logic inputs or an
I2C interface. Connect MODE to GND to control the
device using the direct-control bits. Connect MODE to
VDD to control the device using I2C. In I2C mode, the
MAX4814E controls the MAX3845 (see Figure 5).
Analog Signal Levels
Signal inputs over the full voltage range (0V to VDD) 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 I2C 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 VDD
(mode 1) to control the device using the I2C interface.
Direct Control Method (Mode 0)
In mode 0, DA0/DO0 becomes input DA0, DA1/DO1

DA0/DO0
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.
59
DA1/DO1
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.
60
DA2/DO2
Direct-Control Bit I/O. In mode 0 DA2/DO2 is set as an input, DA2, to control switch
connections. In mode 1, DA2/DO2 is set as an output, DO2. The output bits are used to
drive the MAX3845.
61
DB0/DO3
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.
62
DB1
Direct-Control Bit I/O. In mode 0, DB1 is set as an input. In mode 1, DB1 is high
impedance.
63
DB2
Direct-Control Bit I/O. In mode 0, DB2 is set as an input. In mode 1, DB2 is high
impedance.
EP
Exposed Pad. Connect exposed pad to ground. For enhanced thermal dissipation,
connect EP to a copper area as large as possible. Do not use EP as a sole ground
connection.
