Vishay — DG3257: 700 MHz -3dB Bandwidth, Single SPDT Analog Switch

DG3257 is a low RON, high bandwidth analog switch configured in single SPDT. It achieves 5Ω switch on resistance, greater than 700MHz -3dB bandwidth with 5pF load, and a channel to channel crosstalk at -32dB and isolation at -33dB. Fabricated with high density sub micro CMOS process, the DG3257 provides low parasitic capacitance, and handles bidirectional signal flow with minimized phase distortion. Guaranteed 1.4V logic high threshold makes it possible to interface directly with low voltage MCUs.
