MOS technology. It is designed to operate from

1.65V to 3.6V, making this device ideal for
portable applications.
It offers very low ON-Resistance (<5

input is held high and OFF (high impedance state
exists between the two ports) w hen nIN is held
low; the switches nS2 are ON (they are connected
to common Ports Dn) when the nIN input is held
low and OFF (high impedance state exists
between the two ports) when IN is held high.
Additional key features are fast switch ing speed,
Break Before Make Delay Time and Ultra L ow
Power Consumption. All inp uts and outputs are
equipped with protec tion c irc uits against static
discharge, giving them ESD immunity a nd
transient exc es s voltage. It’s available in the
commercial temperature range in TSSOP and
QFN3x3mm package.
