STG3689
Low Voltage 0.9Ω max dual SPDT Switch
with break-before-make feature
Features
■ Low quiescent supply current:
– Max ± 50µA for V_1IN, V_2IN = 1.80V
at V_CC = 4.3V
■ Ultra low power dissipation:
– I_CC = 0.2µA (Max.) at T_A = 85°C, V_IN = 0V
■ Switch S1: Low “ON” resistance V_IN = 0V:
– R_ON = 0.7Ω (Max. T_A =25°C) at V_CC = 4.3V
– R_ON = 0.9Ω (Max. T_A = 25°C) at V_CC = 3V
■ Wide operating voltage range:
– V_CC (OPR) = 1.65V to 4.3V single supply
■ 4.3V Tolerant and 1.8V compatible threshold
on digital control input at V_CC = 1.65 to 4.3V
■ Latch-up performance exceed 300mA (JESD
17)
■ ESD performance (Analog chan. Vs. GND):
HBM >2kV (MIL STD 883 method 3015)
Description
The STG3689 is a high-speed CMOS low voltage
dual analog S.P.D.T. (Single Pole Dual Throw)
switch or 2:1 Multiplexer/Demultiplexer switch
fabricated in silicon gate C²MOS technology. It is
designed to operate from 1.65V to 4.3V, making
this device ideal for portable applications.
The nIN inputs are provided to control the
switches.
TDFN10
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,
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.
