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 157 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. BENEFITS Built on Vishay Siliconix’s proprietary sub-micron high-density 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 nickelpalladium-gold device terminations meet all JEDEC standards for reflow and MSL ratings. • • • • 1.8 to 5.5 V Single Supply Operation Low Ron: 3 Ω at 4.2 V 157 MHz, - 3 dB Bandwidth Low Off-Isolation, - 47 dB at 10 MHz + 1.6 V Logic Compatible RoHS COMPLIANT 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 Range Package MSOP-10 - 40 to 85 °C DFN-10 Part Number DG2517DQ-T1-E3 DG2518DQ-T1-E3 DG2517DN-T1-E4 DG2518DN-T1-E4 Top View Document Number: 74333 S-61774-Rev.
