STG3820

STG3820 Low voltage high bandwidth quad DPDT switch Features ■ ■ Ultra low power dissipation: – ICC = 1 µA (max) at TA = 85 °C Low "ON" resistance: – RON = 5.4 Ω (TA = 25 ºC) at VCC = 4.3 V – RON = 6.6 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 4 select pins controlling 2 switches each Typical bandwidth (-3 dB) at 800 MHz on all channels USB (2.0) high speed (480 Mbps) signal switching compliant Integrated fail safe function Latch-up performance exceeds 100 mA per JESD 78, Class II ESD performance exceeds JESD22 2000-V human body model (A114-A) ■ ■ ■ ■ ■ ■ ■ ■ Flip-chip 30 (2.0 x 2.4 mm) Description The STG3820 is a high-speed CMOS low voltage quad analog DPDT (dual 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 SELm-n input is provided to control the switches. The switches nS1 and mS1 are ON (connected to common ports Dn and Dm respectively) when the SELm-n input is held high and OFF (high impedance state exists between the two ports) when SELm-n is held low. The switches nS2 and mS2 are ON (connected to common port Dn and Dm respectively) when the SELm-n input is held low and OFF (high impedance state exists between the two ports) when SELm-n is held high.
