... Rev 1; 10/98 8-Channel/Dual 4-Channel Multiplexers General Description The MAX349/MAX350 are 8-channel and dual 4-channel serially controlled multiplexers (muxes). These muxes conduct equally well in either direction. On-resistance (100Ω max) is matched between switches to 16Ω max and is flat (10Ω max) over the specified signal range. ...

... FOUR CLOCK PULSES Figure 7. Differential Multiplexer Input Control Power-Supply Considerations The MAX349/MAX350 construction is typical of most CMOS analog switches. It has three supply pins: V+, V- and GND. V+ and V- are used to drive the internal CMOS switches, and they set the limits of the analog voltage on any switch. Reverse ESD-protection diodes are internally connected between each analog signal pin and both V+ and V- ...

... The V+ and V- supplies need not be symmetrical, but their sum cannot exceed the absolute maximum rating of 17V. Do not connect the MAX349/MAX350 V+ to +3V and connect the logic- level pins to TTL logic-level signals. This exceeds the absolute maximum ratings and can damage the part and/or external circuits ...
