Description
The STG3684A is a high-speed CMOS dual
analog SPDT (single-pole dual-throw) switch or
dual 2:1 multiplexer/demultiplexer bus switch
fabricated using silicon gate C2MOS technology.
Designed to operate from 1.65 to 4.3 V, this
device is ideal for portable applications.
Table 1.
It offers very low ON resistance (RON < 0.5 Ω) at
VCC = 3.0 V. The nIN inputs are provided to
control the independent channel switches nS1
and nS2. The switches nS1 are ON (connected to
common ports Dn) when the nIN input is held high
and OFF (state of high impedance exists between
the two ports) when nIN is held low. The switches
nS2 are ON (connected to common ports Dn)
when the nIN input is held low and OFF (state of
high impedance exists between the two ports)
when IN 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 and
excess transient voltage immunity.

Maximum rating
Stressing the device above the rating listed in the “Absolute maximum ratings” table may
cause permanent damage to the device. These are stress ratings only and operation of the
device at these or any other conditions above those indicated in the Operating sections of
this specification is not implied. Exposure to absolute maximum rating conditions for
extended periods may affect device reliability. Refer also to the STMicroelectronics SURE
Program and other relevant quality documents.
