CMOS, Low Voltage, 2 Wire, Serially Controlled Single 8 to 1 Matrix Switch
Each channel is controlled by one bit of an 8-bit word. This means that these devices may be used in a number of different configurations; all, any, or none of the channels may be on at any one time.
On power-up of the device, all switches will be in the OFF condition and the internal shift register will contain all zeros.
All channels exhibit break-before-make switching action preventing momentary shorting when switching channels.
