STG3482QTR

STG3482 Low voltage dual SP4T switch Features ■ Ultra low power dissipation: – ICC = 0.1 μA (max.) at TA = 25 °C ■ Low “ON” resistance: – RON = 4.6 Ω (TA = 25 °C) at VCC = 4.3 V – RON = 5.8 Ω (TA = 25 °C) at VCC = 3.0 V ■ Wide operating voltage range: – VCC (Opr) = 1.65 to 4.3 V single supply QFN16L (2.6 x 1.8 mm) ■ 4.3 V tolerant and 1.8 V compatible threshold on digital control input at VCC = 2.3 to 3.0 V ■ Typical bandwidth (-3dB) at 300 MHz on all channels ■ Latch-up performance exceeds 300 mA per JESD 78, Class II ■ ESD performance exceeds JESD22 – 2000-V Human body model (A114-A) Description The STG3482 is a high-speed CMOS low voltage dual analog SP4T (single pole four throw) switch or 4:1 multiplexer/demultiplexer switch fabricated in silicon gate C2MOS technology. It is designed to operate from 1.65 to 4.3 V, making this device ideal for portable applications. By controlling the SEL1 and SEL2, one of the independent channels will be connected to the common channel. An /OE pin is also available in this device to disconnect all the switches. 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.
