1 / 13 page 1 +1.8V to +5.5V, 2.5Ω, Single SPDT Analog Switch ISL54503 The Intersil ISL54503 device is a low ON-resistance, low voltage, bidirectional, single pole/double throw (SPDT) analog switch designed to operate from a single +1.8V to +5.5V supply. Targeted applications include battery powered equipment that benefit from low ON-resistance (2.5Ω) and fast switching speeds (tON = 25ns, tOFF = 15ns). 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 ISL54503 is offered in a 6 Ld 1.2mmx1.0mmx0.4mm pitch µTDFN package and a 6Ld SOT-23 package, alleviating board space limitations. The ISL54503 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.
