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.
Any, all or none of the eight switches may be closed at any
given time. Combining low on-resistance (r
and fast switching (t
suited for data acquisition, process control, communication,
and avionic applications.
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. RS resets the shift register, forcing all latch inputs to
a low condition (all switches off). The serial input (D

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.
Each channel conducts equally well in either direction when on
and blocks up to rail-to-rail voltages when off.
