ISL43145

DATASHEET ISL43143, ISL43144, ISL43145 Low-Voltage, Single and Dual Supply, Quad SPST, High Performance Analog Switches FN6037 Rev 4.00 Aug 31, 2017 The Intersil ISL43143–ISL43145 devices are CMOS, precision, quad SPST analog switches designed to operate from a single +2V to +12V supply or from a 2V to 6V supply. Targeted applications include battery powered equipment that benefit from the devices’ low power consumption (<1W), low leakage currents (5nA max), and fast switching speeds (tON = 52ns, tOFF = 40ns). A 5 maximum RON flatness ensures signal fidelity, while channel-to-channel mismatch is guaranteed to be less than 2. The ISL43143/ISL43144/ISL43145 are quad single-pole/ single-throw (SPST) devices. The ISL43143 has four normally closed (NC) switches; the ISL43144 has four normally open (NO) switches; the ISL43145 has two NO and two NC switches and can be used as a dual SPDT, or a dual 2:1 multiplexer. Table 1 summarizes the performance of this family. TA...
