STG3699B
Low Voltage 0.5 Max, Quad SPDT Switch with break-before-make feature
Features
High speed: - tPD = 1.5ns (TYP.) at VCC = 3.0V - tPD = 1.5ns (TYP.) at VCC = 2.3V Ultra low power dissipation: - ICC = 0.2A (MAX.) at TA = 85C Low "ON" Resistance VIN=0V: - R ON = 0.50(MAX. TA = 25C)at VCC=4.3V - R ON = 0.55(MAX. TA = 25C)at VCC=3.0V - R ON = 0.55(MAX. TA = 25C)at VCC=2.7V QFN16L (2.6x1.8)
Wide operanding voltage range: - VCC (OPR) = 1.65V to 4.3V Single supply 4.3V Tolerant and1.8V compatible thresholds on digital control input at VCC = 2.3 to 3.0V Latch-up performance exceed 300mA (JESD 17) ESD performance (analog chan. Vs. GND): HBM > 2kV (MIL STD 883 method 3015)
Description
The STG3699B is a high-speed CMOS low voltage quad analog SPDT (Single-Pole/Double 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.
It offers very low ON-Resistance (RON) (<0.5) at VCC=3.0V. The nIN inputs are provided to control the switches. 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, 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. It is available in the commercial temperature range -40 to 125C in QFN16 2.6x1.8mm package.

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. Table 3.
