MAX4565/MAX4566/MAX4567 19-1252 Rev 0 7/97 Quad/Dual, Low-Voltage, Bidirectional RF/Video Switches General Description Features The MAX4565/MAX4566/MAX4567 are low-voltage High 50 Off Isolation: -83dB at 10MHz T-switches designed for switching RF and video signals Low 50 Crosstalk: -87dB at 10MHz from DC to 350MHz in 50 and 75 systems. The MAX4565 contains four normally open single-pole/single- DC to 350MHz -3dB Signal Bandwidth throw (SPST) switches. The MAX4566 contains two dual 60 Signal Paths with 5V Supplies SPST switches (one normally open, one normally closed.) The MAX4567 contains two single-pole/double-throw 2.5 Signal-Path Matching with 5V Supplies (SPDT) switches. 2 Signal-Path Flatness with 5V Supplies Each switch is constructed in a T configuration, ensuring Low 50 Insertion Loss: 2.5dB at 100MHz excellent high-frequency off isolation and crosstalk of -83dB at 10MHz. They can handle Rail-to-Rail analog sig- 2.7V to 6V Dual Supplies nals in either direction. On-resistance (60 max) is +2.7V to +12V Single Supply matched between switches to 2.5 max and is flat (2 Low Power Consumption: <1W max) over the specified signal range, using 5V supplies. The off leakage current is less than 5nA at +25C and Rail-to-Rail Bidirectional Signal Handling 50nA at +85C.

Limit forward diode current to maximum cur- rent 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.
