Low voltage 1.0

Ω max dual SP3T switch

with break-before-make feature

Features

■ High speed:

–tPD = 0.3 ns (typ.) at VCC =3.0 V

–tPD = 0.4 ns (typ.) at VCC =2.3 V

■ Ultra low power dissipation:

–ICC =0.2 µA (max.) at TA =85°C

■ Low ON resistance VIN =0V:

–RON =1.0 Ω (max. TA =25°C) at

VCC =4.3 V

–RON =1.5 Ω (max. TA =25°C) at

VCC =3.0 V

–RON =1.8 Ω (max. TA =25°C) at

VCC =2.3 V

■ Wide operating voltage range:

–VCC (opr) = 1.65 V 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 4.3 V

■ Latch-up performance exceeds 300 mA

(JESD 17)

■ ESD performance (analog channel vs. GND):

HBM > 2 kV (MIL STD 883 method 3015)

Description

The STG3856 is a high-speed CMOS low voltage

dual analog SP3T (single pole triple throw) switch

or dual 3 : 1 multiplexer /demultiplexer switch

fabricated in silicon gate C2MOS technology. It is

designed to operate from 1.65 V to 4.3 V, making

this device ideal for portable applications.

The device offers very low ON resistance

(< 1.0

Ω) at VCC = 4.3 V. The disabling and

enabling of switches are done by setting the 1IN

and 2IN control pins. Additional key features are

fast switching speed, 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.
