ISL43210A

Medium-Voltage, Single Supply, Single SPDT Analog Switch

Product Status: Mass Production

OVERVIEW

The Intersil ISL43210A device is a precision, bidirectional, single SPDT analog switch designed to operate from a single +2.7V to +15V supply. Targeted applications include applications that require a +15V single supply such as 3D TV/Eyeware products and single supply +3.0V/+5V battery powered equipment that benefit from the devices low power consumption (5µW), low leakage currents (10nA max), and fast switching speeds (tON = 28ns, tOFF = 20ns). Cell phones, for example, often face ASIC functionality limitations. The number of analog input or GPIO pins may be limited and digital geometries are not well suited to analog switch performance. This device may be used to mux-in additional functionality while reducing ASIC design risk. Its small package alleviates board space limitations, making it an ideal solution.

The ISL43210A is a single committed SPDT, which is perfect for use in 2-to-1 multiplexer applications.
