Description
The STG4260 is a high-speed CMOS low voltage
dual analog SPDT (single pole dual throw) switch
or 2:1 multiplexer/demultiplexer switch fabricated
in silicon gate C²MOS technology. It is designed
to operate from 1.65 V to 4.8 V, making this device
ideal for portable applications. It offers low ON-
resistance (0.40 Ω typ.) at V_CC = 4.3 V. The SEL
inputs are provided to control the switches.
The switch S1 is ON (connected to common port
D) when the SEL input is held high and OFF (high
impedance state exists between the two ports)
when SEL is held low; the switch S2 is ON (it is
connected to common Port D) when the SEL input
is held low and OFF (high impedance state exists
between the two ports) when SEL 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.
