... 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. Each switch is constructed in a “ ...

... 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 ...

... Voltages below -0.3V can be clipped by the internal ESD-protection diodes, and the parts can be damaged if excessive current flows. When power to the MAX4565/MAX4566/MAX4567 is off (i.e and V- = 0V), the Absolute Maximum Ratings still apply. This means that neither logic-level inputs on IN_ nor signals on COM_, NO_, or NC_ can exceed ± ...

The MAX4567 has two V+ and two V- pins. Make DC connections to only one of each to minimize crosstalk. Do not route DC current into one of the pins and out the other ...
