DATASHEET ISL84541, ISL84544 FN6016 Rev.8.0 Low-Voltage, Single Supply, Dual SPST, SPDT Analog Switches Feb 25, 2021 The ISL84541 and ISL84544 devices are precision, dual Features analog switches designed to operate from a single +2.7V to Drop-in Replacements for MAX4541, MAX4544, DG9263 +12V supply. Targeted applications include battery powered equipment that benefit from the devices low power Fully Specified at 3.3V and 5V Supplies consumption (5W), low leakage currents (100pA max), and Pin Compatible with MAX323 fast switching speeds (t = 35ns, t = 25ns). Cell phones, ON OFF ON Resistance (R ) 30 for example, often face ASIC functionality limitations. The ON number of analog input or GPIO pins may be limited and R Matching Between Channels <1 ON digital geometries are not well suited to analog switch Low Charge Injection 5pC (Max) performance. This family of parts may be used to mux-in additional functionality while reducing ASIC design risk. Some Single Supply Operation . +2.7V to +12V of the smallest packages are available alleviating board space Low Power Consumption (P ) <5W D limitations. o Low Leakage Current (Max at 85 C) 10nA The ISL84541 is a dual single-pole/single-throw (SPST) Fast Switching Action device. The ISL84541 has two normally open (NO) switches. The ISL84544 is a committed SPDT, which is perfect for use -t 35ns ON in 2-to-1 multiplexer applications. -t . 25ns OFF Table 1 summarizes the performance of this family.
