STG3482

Low voltage dual SP4T switch

Features

■ Ultra low power dissipation:

–ICC =0.1 μA (max.) at TA =25°C

■ Low “ON” resistance:

–RON =4.6 Ω (TA = 25 °C) at VCC =4.3 V

–RON = 5.8 Ω (TA = 25 °C) at VCC =3.0 V

■ Wide operating voltage range:

–VCC (Opr) = 1.65 to 4.3 V single supply

■ 4.3 V tolerant and 1.8 V compatible threshold

on digital control input at VCC = 2.3 to 3.0 V

■ Typical bandwidth (-3dB) at 300 MHz on all

channels

■ Latch-up performance exceeds 300 mA per

JESD 78, Class II

■ ESD performance exceeds JESD22

– 2000-V Human body model (A114-A)

Description

The STG3482 is a high-speed CMOS low voltage

dual analog SP4T (single pole four throw) switch

or 4:1 multiplexer/demultiplexer switch fabricated

in silicon gate C2MOS technology. It is designed

to operate from 1.65 to 4.3 V, making this device

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.
