Description

The DG884 contains a matrix of 32 T-switches configured in an 8 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.
