MAX4562/MAX4563
Serially Controlled, Clickless
Audio/Video Switches

______________________________________________________________________________________
Detailed Description
The MAX4562/MAX4563 are serial-interface controlled
switches with soft-mode “clickless” and hard-mode oper-
ating capability. The MAX4562/MAX4563 contain two
SPST switches and two SPDT switches. The SPDT
switches are actually 2-to-1 multiplexers, in that each
SPDT is really two independent SPST switches with a
common node, as shown in the
Pin Configuration. Each
switch is controlled independently by either the 2-wire
I2C-compatible or 3-wire SPI/QSPI/MICROWIRE-compat-
ible serial interface.
Audio off-isolation and crosstalk is -85dB at 20kHz.
Video off-isolation and crosstalk is at least -55dB at
10MHz.
Each switch of either device may be set to operate in
either soft or hard mode. In soft mode, the switching
transition is slowed to avoid the audible “clicking” that
can occur when switches are used to route audio sig-
nals. In hard mode, the switches are not slowed down,
making this mode useful when a faster response is
required. If a new command is issued while any soft-
mode switch is transitioning, the switch transition time is
decreased so it reaches its final state before the new
command is executed. Soft mode and open are the
power-up default states for all switches. Switches in the
same mode are guaranteed to be break-before-make
relative to each other. Break-before-make does not apply
between switches operating in different modes.
These devices operate from a +2.7V to +5.5V single
supply. The MAX4562 features a 2-wire I2C-compatible
serial interface, and the MAX4563 features a 3-wire
SPI/QSPI/MICROWIRE-compatible serial interface.
