MAX4584

19-1521; Rev 0; 8/99 Serially Controlled Audio/Video Switches General Description The MAX4584/MAX4585 serial-interface, programmable switches are ideal for multimedia applications. Each device contains one normally open (NO) single-pole/ single-throw (SPST) switch and one single-pole/doublethrow (SPDT) switch. The MAX4584/MAX4585 feature 65 Ω on-resistance, 4 Ω on-resistance matching between channels, and 5 Ω on-resistance flatness. Additionally, they have off-isolation of -83dB at 20kHz and -48dB at 10MHz, with crosstalk of -84dB at 20kHz and -60dB at 10MHz. The MAX4584 uses a 2-wire I2C™-compatible serial interface; the MAX4585 uses a 3-wire SPI™/QSPI™/ MICROWIRE™-compatible interface. Both devices are available in a 10-pin µMAX package and are specified for the extended-industrial (-40°C to +85°C) temperature range. o SPST and SPDT Switches o 65Ω (max) RON with +5V Supply o Audio Performance -83dB Off-Isolation at 20kHz -84dB Crosstalk at 20kHz o Video Performance -48dB Off-Isolation at 10MHz -60dB Crosstalk at 10MHz o Serial Interface 2-Wire I2C Compatible (MAX4584) 3-Wire SPI/QSPI/MICROWIRE Compatible (MAX4585) Features o +2.7V to +5.5V Single-Supply Operation MAX4584/MAX4585 Applications Cellular Phones and Accessories Private Mobile Radios (PMRs) PC Multimedia Audio/Video Routing Industrial Equipment Set-Top Boxes Video Conferencing High-End Audio Equipment Ordering Information PART MAX4584EUB MAX4585EUB TEMP.
