STG3220

STG3220 Low voltage high bandwidth dual SPDT switch Features ■ Ultra low power dissipation: – ICC = 1 μA (max.) at TA = 85 °C ■ Low "ON" resistance: – RON = 4.8 Ω (TA = 25 ºC) at VCC = 4.3 V – RON = 5.9 Ω (TA = 25 ºC) at VCC = 3.0 V ■ Wide operating voltage range: – VCC (opr) = 1.65 V to 4.3 V ■ 4.3 V tolerant and 1.8 V compatible threshold on digital control input at VCC = 2.3 V to 3.0 V ■ Typical bandwidth (-3 dB) at 800 MHz on all channels ■ USB (2.0) high speed (480 Mbps) signal switching compliant ■ Integrated fail safe function ■ Interrupt function to indicate to the processor that the device is in dedicated port charging mode ■ Latch-up performance exceeds 500 mA per JESD 78, Class II ■ ESD performance exceeds JESD22: – Dn pins: 4000-V human body model (A114-A) – All other pins: 2000-V human body model (A114-A) Applications ■ Mobile phones QFN10 (1.8 x 1.4 mm) Description The STG3220 is a high-speed CMOS low voltage dual analog SPDT (single pole dual throw) switch or 2:1 multiplexer/de-multiplexer switch fabricated in silicon gate C2MOS technology. It is designed to operate from 1.65 V to 4.3 V, making this device ideal for portable applications. The SEL input is provided to control the switch. The switch nS1 is ON (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 nS2 is ON (it is connected to common port Dn) when the SEL input is held low and OFF (high impedance...
