MAX4562/MAX4563 19-1461 Rev 0 4/99 Serially Controlled, Clickless Audio/Video Switches General Description Features The MAX4562/MAX4563 serial-interface controlled Selectable Soft-Switching Mode for Clickless switches are ideal for multimedia applications. Each Audio Operation device features 30 max on-resistance (R ), 5 R ON ON 30 max On-Resistance match, and 5 R flatness. Audio off-isolation and ON crosstalk at 20kHz is -85dB, and video off-isolation and Audio Performance crosstalk at 10MHz is -55dB. Both devices feature -85dB Off-Isolation at 20kHz clickless mode operation for audio applications. -85dB Crosstalk at 20kHz The MAX4562/MAX4563 contain two normally open sin- -0.007% THD gle-pole/double-throw (SPDT) switches and two normal- Video Performance ly open single-pole/single-throw (SPST) switches. The 2 -55dB Off-Isolation at 10MHz MAX4562 features a 2-wire I C-compatible serial interface. The MAX4563 features a 3-wire SPI/QSPI/ -55dB Crosstalk at 10MHz MICROWIRE-compatible serial interface. Both parts T-Switch Configurable for Improved Off-Isolation are available in 16-pin QSOP packages and operate Serial Interface over the commercial and extended temperature 2 ranges. 2-Wire I C-Compatible (MAX4562) 3-Wire SPI/QSPI/MICROWIRE-Compatible (MAX4563) Single-Supply Operation from +2.7V to +5.5V Applications Set-Top Boxes PC Multimedia Boards Audio Systems Ordering Information Video Conferencing Systems PART TEMP.

Limit forward-diode current to maxi- mum 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. ELECTRICAL CHARACTERISTICSSingle +5V Supply (V+ = +5V 5%, T = T to T , unless otherwise noted.
