Vishay DG485
The DG485 is an analog switch array consisting of eight SPST switches connected to a common output. This device may be used as an 8-channel multiplexer in serial control applications. Combining low on-resistance (rDS(on) 55 W, typ.) and fast switching (tON: 170 ns, typ.), the DG485 is ideally suited for data acquisition, process control, communication, and avionic applications.- Max Voltage : 25V
- Channels : 8
- Max Operating Temp : 125°C
- Min Operating Temp : -55°C

Any, all or none of the eight switches may be closed at any given time. serial output (DOUT) allow daisy chaining of multiple arrays for large systems. Built on the Vishay Siliconix high voltage silicon gate process the DG485 has a wide 44-V power supply voltage rating. An epitaxial layer prevents latchup. Control data is input serially into the shift register with each clock pulse. The shift register contents can be latched-in (via LD) at any point into an octal latch which in turn controls all switches.
