... Rev 1; 5/01 General Description The MAX4529 is a low-voltage T-switch designed for switching RF and video signals from DC to 300MHz in 50Ω and 75Ω systems. This switch is constructed in a “T” configuration, ensuring excellent high-frequency off isolation of -80dB at 10MHz. The MAX4529 can handle Rail-to-Rail in either direction. On-resistance (70Ω ...

... Note 4: Resistance flatness is defined as the difference between the maximum and the minimum value of on-resistance as measured over the specified analog signal range. Note 5: Leakage parameters are 100% tested at the maximum rated hot temperature and guaranteed by correlation at +25°C. Note 6: Guaranteed by design, not subject to production testing in SOT package. ...

... NC and COM pins are identical and interchangeable. Either may be considered as an input or output; signals pass equally well in either direction. Theory of Operation Logic-Level Translators The MAX4529 is constructed as a high-frequency “T” switch, as shown in Figure 1. The logic-level input, IN, is translated by amplifier A1 into logic signal that drives inverter A2. Amplifier A2 drives the gates of N-channel MOSFETs N1 and N2 from V+ to V-, turning them fully on or off ...

... The V+ and V- supplies need not be symmetrical, but their sum cannot exceed the absolute maximum rating of 13.0V. Do not connect the MAX4529 V+ pin to +3V and connect the logic-level Overview 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 ...

... This current can add an unwanted DC bias to the signal. Therefore, when oper- ating V+ above 5V, always drive the IN pin rail-to-rail. When power to the MAX4529 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 or NC can exceed ± ...
