The Intersil ISL54053 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 which benefit from low rON (0. 8Ω) and fast switching speeds (tON = 24ns, tOFF = 10ns). The digital logic input is 1. 8V logic compatible when using a single +3. 0V 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 ISL54053 is offered in the 6 Ld 1. 2mmx1. 0mmx0. 5mm µTDFN and 6 Ld SOT-23 packages, alleviating board space limitations. The ISL54053 is a committed SPDT that consists of one normally open (NO) and one normally closed (NC) switch. This configuration can also be used as a 2-to-1 multiplexer.
