DG211, DG212
Data Sheet June 1999
SPST 4-Channel Analog Switches
The DG211 and DG212 are low cost, CMOS monolithic,
Quad SPST analog switches. These can be used in general
purpose 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
30V
in the OFF condition. The DG211 and DG212 differ
P-P
only in that the digital control logic is inverted, as shown in
the truth table.
