74C906M – NATIONAL SEMICONDUCTOR

The National Semiconductor 74C906M is a quad single-pole, single-throw (SPST) analog switch fabricated using complementary MOS (CMOS) technology. Each switch features break-before-make switching action, minimizing signal distortion during transitions. The device exhibits low on-resistance, typically under 100 ohms, improving signal integrity. Its primary function is to selectively route analog signals, making it suitable for multiplexing, demultiplexing, and sample-and-hold applications. The 74C906M’s output voltage rating is 15V, and it can handle a continuous output current of 25mA per switch. Housed in a 14-pin molded DIP package, it offers ease of integration into through-hole PCB designs. The 74C906M operates reliably across a wide operating temperature range, from –40°C to 85°C. This makes it a robust choice for industrial and instrumentation applications where temperature stability is crucial. Its CMOS construction ensures low power consumption, a significant advantage in battery-powered devices.
