I HIGH SPEED:
t_PD = 0.3ns (TYP.) at V_CC = 3.0V
t_PD = 0.4ns (TYP.) at V_CC = 2.3V
I ULTRA LOW POWER DISSIPATION:
I_CC = 0.2µA (MAX.) at T_A = 85°C
I LOW "ON" RESISTANCE V_IN = 0V:
R_ON = 0.5Ω (MAX. T_A = 25°C) at V_CC = 2.7

the switches. The switches nS1 are ON (they are
connected to common Ports Dn) when the nIN
input is held high and OFF (high impedance state
exists between the two ports) when 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 switching speed,
Break Before Make Delay Time and Ultra Low
Power Consumption. All inputs and outputs are
equipped with protection circuits against static
discharge, giving them ESD immunity and
transient excess voltage. It’s available in the
commercial temperature range in the QFN
package.
