Targeted applications include battery powered equipment that benefit from low rON (0.29Ω) 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. TABLE 1.

VIN = input voltage to perform proper function. 5. The algebraic convention, whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet. 6. Flatness is defined as the difference between maximum and minimum value of on-resistance over the specified analog signal range. 7. rON matching between channels is calculated by subtracting the channel with the highest max rON value from the channel with lowest max rON value, between Nx1 and Nx2. 5 FN6469.0 March 20, 2007 5 Page Die Characteristics SUBSTRATE POTENTIAL (POWERED UP): GND TRANSISTOR COUNT: 114 PROCESS: Submicron CMOS ISL54048, ISL54049 All Intersil U.S. products are manufactured, assembled and tested utilizing ISO9000 quality systems.
