ISL54049

Description

The Intersil ISL54048 and ISL54049 devices are low ON-resistance, low voltage, bidirectional, dual singlepole/ single-throw (SPST) analog switches designed to operate from a single +1.65V to +4.5V supply. Targeted applications include battery powered equipment that benefit from low rON (0.29) and fast switching speeds (tON = 40ns, tOFF = 20ns). The digital logic input is 1.8V logic-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 ISL54048 and ISL54049 are offered in a small form factor package, alleviating board space limitations. The ISL54048 has two normally open (NO) SPST switches and the ISL54049 has two normally closed (NC) SPST switches.
