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
2
MOS technology. Designed to operate from 1.65 to
4.3 V, this device is ideal for portable applications.
QFN16L (2.6 x 1.8 mm)
It offers very low ON resistance (R

CC
< 0.5
= 3.0 V. The nIN inputs are provided to
Ω ) at 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.
The STG3699B is available in the commercial temperature range of -40 to 125°C in a QFN16L,
2.6 x 1.8 mm package.

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
