SPST 4-Channel Analog Switches
The DG211 and DG212 are low cost, CMOS monolithic, Quad SPST analog switches. These can be used in general pur pose switching applications for communications, instrumentation, process control and computer peripheral equipment. Both devices provide true bidirectional performance in the ON condition and will block signals to 30VP-P in the OFF condition. The DG211 and DG212 differ only in that the digital control logic is inverted, as shown in the truth table.
