General Description

The MAX4562/MAX4563 serial-interface controlled
switches are ideal for multimedia applications. Each
device features 30Ω max on-resistance (RON), 5Ω R

ON

match, and 5Ω R

ON

flatness. Audio off-isolation and
crosstalk at 20kHz is -85dB, and video off-isolation and
crosstalk at 10MHz is -55dB. Both devices feature
“clickless” mode operation for audio applications.

The MAX4562/MAX4563 contain two normally open sin­gle-pole/double-throw (SPDT) switches and two normal­ly open single-pole/single-throw (SPST) switches. The
MAX4562 features a 2-wire I2C™-compatible serial
interface. The MAX4563 features a 3-wire SPI™/QSPI™/
MICROWIRE™-compatible serial interface. Both parts
are available in 16-pin QSOP packages and operate
over the commercial and extended temperature
ranges.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
