STG3692
Low voltage high bandwidth quad SPDT switch
Features Ultra low power dissipation: ICC = 0.2 µA (max.) at TA = 85 °C Low “ON” resistance: RON = 4.6 Ω (TA = 25 °C) at VCC = 4.3 RON = 5.8 Ω (TA = 25 °C) at VCC = 3.0
QFN16L (2.6mm x 1.8mm)
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

channels
switch or 2:1 multiplexer/demultiplexer switch
Latch-up performance exceeds 100 m A per

JESD 78, Class II
designed to operate from 1.65 V to 4.3 V, making
ESD performance exceeds JESD22 this device ideal for portable applications. 2000-V human body model (A114-A)
The n SEL inputs are provided to control the
USB (2.0) high-speed (480 Mbps) signal switch. The switch S1 is ON (connected to switching compliant common ports Dn) when the n 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 n SEL input is held low and OFF (high impedance state exists between the two ports) when n 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.
