Serially Controlled, Clickless Audio/Video Switches
General Description
T h e MAX4571MAX4574 serial-interface controlled switches are ideal for multimedia applications. Each device features 35 max on-resistance, -90dB audio o f f - i s o l a t i o n at 20kHz, -60dB video off-isolation at 1 . 0 M H z , and "clickless" mode operation for audio applications. The MAX4571/MAX4573 contain eleven SPST switches, while the MAX4572/MAX4574 contain two SPST switches and six SPDT switches. The MAX4571/MAX4572 feature a 2-wire, I 2CTM-compatible serial interface. The M A X 4 5 7 3 / M A X 4 5 7 4 feature a 3-wire, SPITM/QSPITM/ M I C R O W I R E TM - c o m p a t i b l e serial interface. All four parts are available in 28-pin QSOP, SSOP, and wide SO packages and operate over the commercial and extended temperature ranges.

Note 1: Signals on NO_ _ or COM_ exceeding V+ or V- 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.
