Description

The STG3699B is a high-speed CMOS low
voltage quad analog SPDT (single-pole double­throw) switch or 2:1 multiplexer/demultiplexer
switch fabricated using silicon gate C
technology. Designed to operate from 1.65 to

4.3 V, this device is ideal for portable applications.

with break-before-make feature

It offers very low ON resistance (R
V

= 3.0 V. The nIN inputs are provided to

CC

control the independent channel switches nS1
and nS2. The switches nS1 ar e ON (connected to
common ports Dn) when the nIN input is held high
and OFF (state of high impedance ex ists 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 protec tio n circ uits
against static discharge, giving them ESD and
excess transient voltage immunity.

The STG3699B is available in the commercial

2 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 ot her conditions above those indicated in the Operating sections of
this specification is not implied. Exposure to absolute maximum rating conditions for
extended periods may aff ect device reliability. Refer also to the STMicroelectronics SURE
Program and other relevant quality documents.
