Low voltage dual SP4T switch
Features Ultra low power dissipation: ICC 0.1 μA (max.) at TA °C Low “ON” resistance: RON 4.6 Ω (TA °C) at VCC 4.3 RON 5.8 Ω (TA = 25 °C) at VCC 3.0 Wide operating voltage range: VCC (Opr) = 1.65 to 4.3 V single supply QFN16L (2.6 x 1.8 mm) 4.3 V tolerant and 1.8 V compatible threshold on digital control input at VCC = 2.3 to 3.0
Description
Typical bandwidth (-3d B) at 300 MHz on all channels The STG3482 is a high-speed CMOS low voltage
dual analog SP4T (single pole four throw) switch
Latch-up performance exceeds 300 m A per
or 4:1 multiplexer/demultiplexer switch fabricated
JESD 78, Class II
in silicon gate C2MOS technology. It is designed
ESD performance exceeds JESD22
to operate from 1.65 to 4.3 V, making this device
2000-V Human body model (A114-A) ideal for portable applications.
By controlling the SEL1 and SEL2, one of the independent channels will be connected to the common channel. An /OE pin is also available in this device to disconnect all the switches. 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.
