ISL54048, ISL54049 Data Sheet June 11, 2007 FN6469.1 Ultra Low ON-Resistance, +1.65V to +4.5V, Features Single Supply, Dual SPST Analog Switch ON-Resistance (r ) ON The Intersil ISL54048 and ISL54049 devices are low - V+ = +4.3V 0.29 ON-resistance, low voltage, bidirectional, dual single- - V+ = +3.0V 0.33 pole/single-throw (SPST) analog switches designed to - V+ = +1.8V 0.55 operate from a single +1.65V to +4.5V supply. Targeted r Matching Between Channels . 0.06 ON applications include battery powered equipment that benefit from low r (0.29) and fast switching speeds (t = 40ns, r Flatness Across Signal Range 0.03 ON ON ON tOFF = 20ns). The digital logic input is 1.8V logic-compatible Single Supply Operation . +1.65V to +4.5V when using a single +3V supply. Low Power Consumption (P ) . <0.45W D Cell phones, for example, often face ASIC functionality Fast Switching Action (V+ = +4.3V) limitations. The number of analog input or GPIO pins may be -t . 40ns limited and digital geometries are not well suited to analog ON switch performance. This part may be used to mux-in -t 20ns OFF additional functionality while reducing ASIC design risk. The ESD HBM Rating .>8kV ISL54048 and ISL54049 are offered in a small form factor 1.8V Logic Compatible (+3V supply) package, alleviating board space limitations. Low ICC Current when VinH is not at the V+ Rail The ISL54048 has two normally open (NO) SPST switches and the ISL54049 has two normally closed (NC) SPST Available in 10 Ld 1.8mmx1.4mmx0.5mm TQFN switches.
