... The MAX4565/MAX4566/MAX4567 are low-voltage T-switches designed for switching RF and video signals from DC to 350MHz in 50Ω and 75Ω systems. The MAX4565 contains four normally open single-pole/single- throw (SPST) switches. The MAX4566 contains two dual SPST switches (one normally open, one normally closed.) The MAX4567 contains two single-pole/double-throw (SPDT) switches ...

... Plastic DIP (derate 10.53mW/°C above +70°C) ..........................842mW Note 1: Voltages on all other pins exceeding are clamped by internal diodes. 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 ...

... This produces superior high-frequency signal isolation when the switch is turned off. Logic-Level Translators The MAX4565/MAX4566/MAX4567 are constructed as high-frequency “T” switches, as shown in Figure 1. The logic-level input, IN_, is translated by amplifier A1 into logic signal that drives amplifier A2. (Amplifier inverter for normally closed switches ...

... The V+ and V- sup- plies need not be symmetrical, but their sum cannot exceed the absolute maximum rating of 13.0V. Do not connect the MAX4565/MAX4566/MAX4567 V+ pin to Overview +3V and connect the logic-level input pins to TTL logic-level signals. TTL logic-level outputs can exceed the absolute maximum ratings, causing damage to the part and/or external circuits ...

... IN_ and GND_ pins is less than 1nA, but Power Off increases with switching frequency. On the MAX4565 only, two extra ground pins—GND5 and GND6—are provided to improve isolation and crosstalk. They are not connected to the logic-level cir- cuit. These pins should always be connected to the ground plane with solid copper ...

... V- pin as close to the package as possible. For sin- gle-supply operation, the MAX4567 should have two 10nF bypass capacitors connected (one to each V+ pin) as close to the package as possible. On the MAX4565, GND5 and GND6 should always be connected to the ground plane with solid copper to improve isolation and crosstalk. V+ ...

... Quad/Dual, Low-Voltage, Bidirectional RF/Video Switches With its excellent off isolation, the MAX4565 is ideal for use in high-frequency video multiplexers. Figure 2 shows such an application for switching any one of four video inputs to a single output. The same circuit may be used as a demultiplexer by simply reversing the sig- nal direction ...
