DATASHEET ISL84541, ISL84542, ISL84543, ISL84544 FN6016 Rev 7.00 Low-Voltage, Single Supply, Dual SPST, SPDT Analog Switches August 19, 2015 The Intersil ISL84541ISL84544 devices are precision, dual Features analog switches designed to operate from a single +2.7V to Pb-free Available as an Option +12V supply. Targeted applications include battery powered equipment that benefit from the devices low power Drop-in Replacements for MAX4541 - MAX4544, consumption (5W), low leakage currents (100pA max), and DG9461, DG9262 - DG9263 fast switching speeds (t = 35ns, t = 25ns). Cell phones, ON OFF Fully Specified at 3.3V and 5V Supplies for example, often face ASIC functionality limitations. The Pin Compatible with MAX323 - MAX325 number of analog input or GPIO pins may be limited and digital geometries are not well suited to analog switch ON Resistance (R ) 30 ON performance. This family of parts may be used to mux-in R Matching Between Channels <1 ON additional functionality while reducing ASIC design risk. Some of the smallest packages are available alleviating board space Low Charge Injection 5pC (Max) limitations, and making Intersils newest line of low-voltage Single Supply Operation . +2.7V to +12V switches an ideal solution. Low Power Consumption (P ) <5W D The ISL84541/ISL84542/ISL84543 are dual single- o Low Leakage Current (Max at 85 C) 10nA pole/single-throw (SPST) devices. The ISL84541 has two normally open (NO) switches the ISL84542 has two normally Fast Switching Action closed (NC) switches the ISL84543 has one NO and one NC -t 35ns ON switch and can be used as an SPDT. The ISL84544 is a -t . 25ns OFF committed SPDT, which is perfect for use in 2-to-1 multiplexer Guaranteed Break-Before-Make (ISL84543/ISL84544 applications. only) Table 1 summarizes the performance of this family.
