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. 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 mand. 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 (Fax Back document number 70610). The DG884 is built on a proprietary D/CMOS process that bines 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.
