DG2517/DG2518
Vishay Siliconix
3 Ω, High Bandwidth, Dual SPDT Analog Switch
DESCRIPTION
The DG2517/DG2518 are low-voltage dual single-pole/dou-
ble-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.
FEATURES
• 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
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 high-den-
sity process, the DG2517/DG2518 brings low power con-
sumption at the same time as reduces PCB spacing with the
MSOP10 and DFN10 packages.
As a committed partner to the community and the environ-
ment, 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 stan-
dards for reflow and MSL ratings.
BENEFITS

• Full Rail Signal Swing Range
APPLICATIONS
• USB/UART Signal Switching
• Audio/Video Switching
• Cellular Phone
