The ISL54051 devices is low ON-resistance, low voltage, bidirectional, 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, which benefit from low rON resistance (0.8O), excellent rON flatness, 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 family of parts may be used to switch in additional functionality while reducing ASIC design risk. The ISL54051 are offered in a 6 Ld 1.2mmx1.0mmx0.5mm µTDFN package and a 6 Ld SOT-23 package, alleviating board space limitations. The ISL54051 has one normally open (NO) switch and ISL54052 has one normally closed (NC) switch.
