The NC7SZ66L6X is an analogue switch IC manufactured by ON Semiconductor. It is a single pole, single throw (SPST) switch which is normally open and can operate at low voltage. It is used to switch one input signal to one of two or more outputs, allowing for either a single, simultaneous signal to multiple outputs, or for multiple signals to be switched to a single output. The device features a high signal bandwidth, low on-resistance, low capacitance, and a low-power consumption. This makes it ideal for applications such as signal switching for audio and video, switching of RF signals, signal multiplexing, and high-speed logic devices.
