DG3537/3538/3539/3540 Vishay Siliconix 4-Ω, 360-MHz, Dual SPST Analog Switches DESCRIPTION FEATURES The DG3537/3538/3539/3540 are dual SPST analog switches which operate from 1.8 V to 5.5 V single rail power supply. They are design for audio, video, and USB switching applications. The devices have 4 Ω on-resistance and 360 MHz 3 dB bandwidth. 0.2 Ω on-resistance matching and 1 Ω flatness make the device high linearity. The devices are 1.6 V logic compatible within the full operation voltage range. These switches are built on a sub-micron high density process that brings low power consumption and low voltage performance. The switches are packaged in MICRO FOOT chip scale package of 3 x 3 bump array. • • • • • • 1.8 V to 5.5 V Operation 3 Ω at 2.7 V rON 360 MHz - 3 dB Bandwidth ESD Method 3015.7 > 2 kV Latch-Up Current 0.300 mA (JESD 78) 1.6 V Logic Compatible RoHS COMPLIANT BENEFITS • • • • • As a committed partner to the community and environment, Vishay Siliconix manufactures this product with the lead (Pb)-free device terminations. For MICRO FOOT analog switch products manufactured with tin/silver/copper (SnAgCu) device termination, the lead (Pb)-free "-E1" suffix is being used as a designator.
