MAX4586/MAX4587
Detailed Description
The MAX4586/MAX4587 are serial-interface, programma-
ble multiplexers. Each device contains a 4-to-1 normally
open (NO) multiplexer. Each switch is independently con-
trolled through the on-chip serial interface. The MAX4586
uses a 2-wire, I2C-compatible serial communications
protocol, and the MAX4587 uses a 3-wire, SPI/QSPI/
MICROWIRE-compatible serial communications protocol.
These devices operate from a single +2.7V to +5.5V
supply and are optimized for use with an audio fre-
quency at 20kHz and video frequencies up to 10MHz.
They feature 65
on-resistance, 4 on-resistance
matching between channels, and 5
on-resistance flat-
ness. Audio off-isolation is -83dB at 20kHz and
crosstalk is at least -84dB at 20kHz, while video off-iso-
lation is -48dB at 10MHz and crosstalk is at least -60dB
at 10MHz.
Applications Information
Multiplexer Control
The MAX4586/MAX4587 have a common command-bit
structure; the only difference between them is the inter-
face type (2-wire or 3-wire, respectively).
The command controls the open/closed states of the
various switches. Table 1 shows the configuration of
the data bits and their related switches. After a com-
mand is issued, a logic “1” in any data-bit location clos-
es the associated switch, while a logic “0” opens it
(Table 2).
2-Wire Serial Interface
The MAX4586 uses a 2-wire, I2C-compatible serial
interface. The COM_ register uses the “SendByte” pro-
tocol that consists of an address byte followed by a
command byte (Table 1).
To address a given chip, the A bit in the address byte
must duplicate the value present at the A pin of that chip.
The rest of the address bits must match those shown in
Table 3. The command byte details are described in the
Switch Control section.
The 2-wire serial interface requires only two I/O lines of
a standard microprocessor (P) port. Figures 1 and 2
detail the timing diagram for signals on the 2-wire bus,
and Tables 1 and 3 detail the format of the signals. The
MAX4586 is a receive-only device and must be con-
trolled by the bus master device. A bus master device
communicates by transmitting the address byte of the
slave device over the bus and then transmitting the
desired information. Each transmission consists of a
start condition, an address byte, a command byte, and
finally a stop condition. The slave device acknowledges
the recognition of its address by pulling the SDA line
low for one clock period after the address byte is trans-
mitted. The slave device also issues a similar acknowl-
edgment after the command byte.
