DATASHEET ISL43143, ISL43144, ISL43145 FN6037 Rev 4.00 Low-Voltage, Single and Dual Supply, Quad SPST, High Performance Analog Aug 31, 2017 Switches The Intersil ISL43143ISL43145 devices are CMOS, Features precision, quad SPST analog switches designed to operate Fully Specified for 10% Tolerances at V = 5V and S from a single +2V to +12V supply or from a 2V to 6V supply. V+ = 12V, 5V and 3.3V Targeted applications include battery powered equipment that benefit from the devices low power consumption (<1W), low Four Separately Controlled SPST Switches leakage currents (5nA max), and fast switching speeds Pin Compatible with DG411/DG412/DG413 (t = 52ns, t = 40ns). A 5 maximum R flatness ON OFF ON ON Resistance (R Max.) 25 ensures signal fidelity, while channel-to-channel mismatch is ON guaranteed to be less than 2. R Matching Between Channels <1 ON The ISL43143/ISL43144/ISL43145 are quad single-pole/ Low Power Consumption (P ) <1W D single-throw (SPST) devices. The ISL43143 has four normally Low Off Leakage Current (Max at 85C) . 2.5nA closed (NC) switches the ISL43144 has four normally open (NO) switches the ISL43145 has two NO and two NC Fast Switching Action switches and can be used as a dual SPDT, or a dual 2:1 -t 52ns ON multiplexer. -t . 40ns OFF Table 1 summarizes the performance of this family.
