Description
• This Circuit is Processed in Accordance to MIL-STD- The DG441/883 and DG442/883 monolithic CMOS analog

883 and DG202/883 series devices. They include four inde-
pendent single pole single throw (SPST) analog switches,
TTL and CMOS compatible digital inputs, and a voltage ref-
erence for logic thresholds.

• Low Charge Injection
The improvements in the DG441/883 series are made possi-
ble by using a high voltage silicon-gate process. An epitaxial
layer prevents the latch-up associated with older CMOS
technologies. The 44V maximum voltage range permits con-
trolling 40V peak-to-peak signals. Power supplies may be
single-ended from +5V to +34V, or split from ±5V to ±20V.
• Upgrade from DG201A/883/DG202/883
• TTL, CMOS Compatible
• Single or Split Supply Operation
Applications
• Audio Switching
The four switches are bilateral, equally matched for AC or
bidirectional signals. The ON resistance variation with analog
signals is quite low over a ±5V analog input range. The
switches in the DG441/883 and DG442/883 are identical, dif-
fering only in the polarity of the selection logic.
