GENERAL DESCRIPTION
The
contain four independent
single-pole/single-throw (SPST) switches. The
and
differ only in that the digital control logic is inverted.
The
switches are turned on with Logic 0 on the
appropriate control input, while Logic 1 is required for the
switches. The
has two switches with
digital control logic similar to that of the
the logic is
inverted on the other two switches. Each switch conducts equally
well in both directions when on and has an input signal range that
extends to the supplies. In the off condition, signal levels up to
the supplies are blocked.
The
exhibits break-before-make switching action for use
in multiplexer applications. Inherent in the design is the low charge
injection for minimum transients when switching the digital inputs.
The ultralow on resistance of these switches make them ideal
solutions for data acquisition and gain switching applications
where low on resistance and distortion is critical. The on resistance
profile is very flat over the full analog input range, ensuring
excellent linearity and low distortion when switching audio signals.
The CMOS construction ensures ultralow power dissipation, making
them ideally suited for portable and battery-powered instruments.
