Additional Details:

The MC145040P operates with a supply voltage range of 3V to 18V. It features a typical ON resistance of 150 ohms and an OFF leakage current of 1 nA. The address latch allows the multiplexer to be controlled by a microprocessor or other digital system. The break-before-make switching action ensures that only one channel is connected at a time, preventing signal distortion. The device is available in a 16-pin plastic DIP package.

The digital control inputs are compatible with both TTL and CMOS logic levels, providing flexibility in system design. The low power consumption of the CMOS technology makes it suitable for battery-powered applications. The wide analog signal range allows the multiplexer to handle a variety of analog signals, including audio, video, and instrumentation signals. The device is designed to operate over the industrial temperature range of -40°C to +85°C. It provides robust performance in demanding environments.
