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, I2C™-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.
