Serially Controlled, 4-Channel
Audio/Video Multiplexers
General Description
The MAX4586/MAX4587 serial-interface, programmable,
4-to-1 channel multiplexers are ideal for multimedia
applications. They feature 65Ω on-resistance, 4Ω on-
resistance matching between channels, and 5Ω on-
resistance flatness. Additionally, they feature -83dB
off-isolation at 20kHz and -48dB off-isolation at 10MHz,
with -84dB crosstalk at 20kHz and -60dB crosstalk at
10MHz.
The MAX4586 uses a 2-wire, I
2
C™-compatible serial
interface; the MAX4587 uses a 3-wire, SPI™/QSPI™/
MICROWIRE™-compatible interface. Both devices are
available in 10-pin µMAX packages and are specified
for the extended -40°C to +85°C temperature range.

Note 1:
Signals on NO_ or COM exceeding V+ or ground are clamped by internal diodes. Limit forward-diode current to maximum
current rating.
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.
