The Intersil ISL54501 and ISL54502 devices are low ON-resistance, low voltage, bi-directional, single pole/single throw (SPST) analog switches designed to operate from a single +1.8V to +5.5V supply. Targeted applications include battery powered equipment that benefit from low rON resistance (5Ω), excellent rON flatness, and fast switching speeds (tON = 22ns, 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 family of parts may be used to switch in additional functionality while reducing ASIC design risk. The ISL54501, ISL54502 are offered in a 6 Ld 1.2mmx1.0mmx0.4mm pitch μTDFN package and 6 Ld SOT-23 package, alleviating board space limitations.
The ISL54501 has one normally open (NO) switch and ISL54502 has one normally closed (NC) switch.
