ISL43240 Quad SPDT Analog Switch Renesas Electronics ISL43240 Quad SPDT Analog Switch is designed to operate from a single +2V to +12V supply or from a ±2V to ±6V supply. Targeted applications include battery-powered equipment that benefits from the devices’ low power consumption (5µW), low leakage currents (5nA max), and fast switching speeds (tON = 52ns, tOFF = 40ns). A 5Ω maximum rON flatness ensures signal fidelity, while channel-to-channel mismatch is guaranteed to be less than 2Ω.
