The DG3157E is a high speed single-pole double-throw analog switch designed for +1.65 V to +5.5 V single power rail operation. Fabricated with high density CMOS technology, the DG3157E achieves low on-resistance, fast switching speed, and high bandwidth while maintains low power consumption. The DG3157E can handle both analog and digital signals and permits signals with amplitudes of up to V+ to be transmitted in either direction. When the select pin is low, B0 is connected to the output A pin. When the select pin is high, B1 is connected to the output A pin.
