STG3693 Datasheet Low voltage high bandwidth quad SPDT switch Features Ultra low power dissipation: QFN16L I = 0.3 A at T = 125 C CC A (2.6x1.8 mm) Low on-resistance: R = 4 (T = 25 C) at V = 3.0 V DS(on) A CC Wide operating voltage range: V (opr) = 1.65 V to 5 V single supply CC 5 V tolerant and 1.8 V compatible threshold on digital control input at V = 2.3 CC V to 3.0 V Typical bandwidth (-3 dB) at 800 MHz on all channels Latch-up performance exceeds 100 mA per JESD 78, Class II ESD performance exceeds JESD22 2000-V human body model (A114-A) USB (2.0) high speed (480 Mbps) signal switching compliant Description The STG3693 is a high-speed CMOS low voltage quad analog SPDT (single pole dual throw) switch or 2:1 multiplexer /demultiplexer switch fabricated in silicon gate C2MOS technology. It is designed to operate from 1.65 V to 5 V, making this device ideal for portable applications. Product status link The nSEL inputs are provided to control the switch. The switch S1 is ON (it is STG3693 connected to common ports Dn) when the nSEL input is held high and OFF (high impedance state exists between the two ports) when SEL is held low the switch S2 Product summary is ON (it is connected to common port D) when the nSEL input is held low and OFF (high impedance state exists between the two ports) when nSEL is held high. Order code STG3693QTR Additional key features are fast switching speed, break-before-make delay time and QFN16L (2.6x1.8 ultra low power consumption. All inputs and outputs are equipped with protection PackageQFN16L mm) circuits against static discharge, giving them ESD immunity and transient excess voltage.
