.vishay. Vishay Siliconix Powered-off Isolation, 0.86 , 1.65 V to 5.5 V, SPDT Analog Switch (2:1 Multiplexer) DESCRIPTION The DG4157E is a high performance single-pole, double-throw (SPDT) analog switch designed for 1.65 V to 5.5 V operation with a single power rail. Fabricated with high density CMOS technology, the device achieves low on resistance of 0.86  at a 4.5 V power supply, low power consumption, and fast switching speeds.  The DG4157E can handle both analog and digital signals and permits signals with amplitudes of up to V+ to be transmitted in either direction. Its control logic inputs can go over V+ up to 5.5 V. The control logic input high threshold is guaranteed as low as 1.8 V over the power supply range up to 5.5 V. It Features break before make switching performance. Its -3 d B bandwidth is typically 152 MHz. A powered-off protection circuit is built into the switch to prevent an abnormal current flow from pin to V+ during the...
