    All devices contain diodes to protect inputs against damage due  
    to high static voltages or electric fields; however, it is advised that  
    precautions be taken not to exceed the maximum recommended  
    input voltages. All unused inputs must be connected to an  
    appropriate logic level (either Vcc or GND).

    f - Frequency (MHz)  
    By inserting 1K ohm resistors in series with V+ and V-  
    power supply lines and decoupling both pins at the device  
    socket, it is possible to improve power supply rejection  
    ratios of a video switch by 50dB at frequencies of 20MHz  
    and higher.

    This circuit provides very low distortion ( <0.1%) and  
    high off isolation ( >90 dB) at signal levels equal to the  
    supply voltage. The signal passes through a T switch  
    configuration and at the same time is modulating the  
    power supply. This modulation maintains a constant on  
    resistance rDS(on) which in turn reduces the distortion.  
    R5 is for bypassing the power supply and has a typical  
    value of 1K ohm, R4 should be a value that can be  
    accommadated by the signal source as load, R3 is only  
    necessary at loads lower than 100 ohms and should be  
    selected during the initial design of the circuit, C1 has  
    to be large enough for the lowest signal to pass and C2  
    will have to bypass all signals. R1 and R2 set up the  
    one logic level for the control input and should be set to  
    5 volts.

    LOGIC INVERTER  
    This circuit provides logic inversion with two resistors  
    and one switch. It does not require additional logic  
    parts. The resistors divide the supply voltage down to  
    a 5 volt level when high and are switched to a low level  
    via the switch. This configuration allows a single pole,  
    single throw switch to be changed into a single pole,  
    double throw switch.
