DG2517, DG2518 Vishay Siliconix 3-Ω, High Bandwidth, Dual SPDT Analog Switch DESCRIPTION FEATURES The DG2517, DG2518 are low-voltage dual single-pole/ double-throw monolithic CMOS analog switches. Designed to operate from 1.8 V to 5.5 V power supply, the DG2517, DG2518 achieves a bandwidth of 242 MHz while providing low on-resistance (3 Ω), excellent on-resistance matching (0.2 Ω) and flatness (1 Ω) over the entire signal range. The DG2517, DG2518 offers the advantage of high linearity that reduces signal distortion, making ideal for audio, video, and USB signal routing applications. Additionally, the DG2517, DG2518 are 1.6 V logic compatible within the full operation voltage range. Built on Vishay Siliconix’s proprietary sub-micron highdensity process, the DG2517, DG2518 brings low power consumption at the same time as reduces PCB spacing with the MSOP10 and DFN10 packages. As a committed partner to the community and the environment, Vishay Siliconix manufactures this product with the lead (Pb)-free device terminations. The DFN package has a nickel-palladium-gold device termination and is represented by the lead (Pb)-free "-E4" suffix. The MSOP package uses 100 % matte Tin device termination and is represented by the lead (Pb)- free "-E3" suffix. Both the matte Tin and nickel-palladium-gold device terminations meet all JEDEC standards for reflow and MSL ratings. • 1.8 V to 5.5 V single supply operation • Low RON: 3 Ω at 4.2 V • 242 MHz, - 3 dB bandwidth • Low off-isolation, - 51 dB at 10 MHz • + 1.6 V logic compatible RoHS COMPLIANT BENEFITS • • • • High linearity Low power consumption High bandwidth Full rail signal swing range APPLICATIONS • • • • • • • USB/UART signal switching Audio/video switching Cellular phone Media players Modems Hard drives PCMCIA FUNCTIONAL BLOCK DIAGRAM AND PIN CONFIGURATION DG2517 IN1 1 10 COM1 NO1 2 9 NC1 GND 3 8 V+ Logic NC1 and NC2 NO1 and NO2 NO2 4 7 NC2 0 ON OFF 6 COM2 1 OFF ON IN2 5 TRUTH TABLE Top View DG2518 IN1 1 10 COM1 NC1 2 9 NO1 GND 3 8 V+ NC2 4 7 NO2 IN2 5 6 COM2 ORDERING INFORMATION Temp.
