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.
