ProTek Analog’s PA4684 is a dual high-bandwidth, fast
single-pole double throw (SPDT) CMOS switch. It can be
used as an analog switch or as a low-delay bus switch.
Specified over a wide operating power supply voltage, 1.65V
to 5.5V, the PA4684 has a maximum On-Resistance of 0.5Ω
at +2.7V.
Break-before-make switching prevents both switches being
enabled simultaneously. This eliminates signal disruption
during switching.
The control input, INX, tolerates input drive signals up to
6.0V, independent of supply voltage.

Notes:
1.
"Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the
device at these or any other conditions beyond those indicated in the operational sections of this specification is not implied.
2.
The input and output negative voltage ratings may be exceeded if the input and output diode current ratings are observed.
3.
Control input must be held HIGH or LOW; it must not float.
