ISL43L210

Ultra Low ON-Resistance, +1.1V to +4.5V Single Supply, SPDT Analog Switch

Product Status: Mass Production

OVERVIEW

The Intersil ISL43L210 device is a low ON-resistance, low voltage, bidirectional, single pole/double throw (SPDT) analog switch designed to operate from a single +1.1V to +4.5V supply. Targeted applications include battery powered equipment that benefit from low on-resistance and fast switching speeds (tON = 7ns, tOFF = 3ns). The digital logic input is 1.8V CMOS compatible when using a single +3V supply.

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 part may be used to "mux-in" additional functionality while reducing ASIC design risk. The ISL43L210 is offered in a 6 lead SC70 package, alleviating board space limitations.

The ISL43L210 is a committed SPDT that consist of one normally open (NO) and one normally closed (NC) switch. This configuration can also be used as a 2-to-1 multiplexer.
