STG3155DTR STMicroelectronics

STG3155 Low voltage 0.5 Max single SPDT switch with break-before-make feature Features High speed: t = 1.5ns (Typ.) at V = 3.0V PD CC t = 1.5ns (Typ.) at V = 2.3V PD CC Ultra low power dissipation: I = 0.2A (Max.) at T = 85C CC A LowO resistance: DFN6L R = 0.5 (T = 25C) at V = 4.3V ON A CC R = 0.6 (T = 25C) at V = 3.0V ON A CC R = 1.0 (T = 25C) at V = 1.8V Description ON A CC Wide operating voltage range: The STG3155 is a high-speed CMOS low voltage V (OPR) = 1.65V to 4.3V single supply CC single analog S.P.D.T. (Single Pole Dual Throw) switch or 2:1 Multiplexer /Demultiplexer switch 4.3V Tolerant and 1.8V compatible threshold 2 fabricated in silicon gate C MOS technology. It is on digital control input at V = 2.3V to 3.0V CC designed to operate from 1.65V to 4.3V, making Latch-up performance exceeds 300mA (JESD this device ideal for portable applications. 17) The device offers very low ON-Resistance ESD Performance (Analog Chan. Vs. GND): (<0.5) at V = 4.3V. The SEL inputs are CC HMB >2kV (MIL STD 883 method 3015) provided to control the switch. The switch S1 is ON (they are connected to common Ports Dn) when the SEL input is held high and OFF (high impedance state exists between the two ports) when SEL is held low the switch S2 is ON (it is connected to common Port D) when the SEL input is held low and OFF (high impedance state exists between the two ports) when SEL 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. Table 1.
