The DG4157 is a high performance single pole double throw analog switch designed for 1.65 V to 5.5 V operation with single power rail. Fabricated with high density CMOS technology, the device achieves low on resistance as 1 Ω at 4.5 V power supply and fast switching speed. The - 3 dB bandwidth is typically 117 MHz. The DG4157 features break before make switch performance, and guarantees logic high control input threshold as low as 1.4 V over the range up to 5.5 V. It can handle both analog and digital signals and permits signals with amplitudes of up to VCC to be transmitted in either direction. Power down protection circuit is built in to prevent abnormal current path through signal pins during power down condition. Each output pin (A, B0, or B1) can withstand greater than 8 kV (human body model). It is available in both SC-70-6 and miniQFN6 packages. The features make it an ideal part for the switching of audio, video, and data stream.
