DESCRIPTION
The DG884 contains a matrix of 32 T-switches configured in
an 8 x 4 crosspoint array. Any of the IN/OUT pins may be
used as an input or output. Any of the IN pins may be
switched to any or simultaneously to all OUT pins.
The DG884 is built on a proprietary D/CMOS process that
combines low capacitance switching DMOS FETs with low
power CMOS control logic and drivers. The ground lines
between adjacent signal input pins help to reduce crosstalk.
The low on-resistance and low on-capacitance of the DG884
make it ideal for video and wideband signal routing.
Control data is loaded individually into four Next Event
latches. When all Next Event latches have been
programmed, data is transferred into the Current Event
latches via a SALVO command. Current Event latch data
readback is available to poll array status.
Output disable capabilities make it possible to parallel
multiple DG884s to form larger switch arrays. DIS outputs
provide control signals used to place external buffers in a
power saving mode.
For additional information see applications note AN504
(FaxBack document number 70610).
