The improvements in the DG401/403/405 series are made
possible 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
• Low Charge Injection
• DG401 Dual SPST; Same Pinout as HI-5041
• DG403 Dual SPDT; DG190, IH5043, IH5151, HI-5051
• DG405 Dual DPST; DG184, HI-5045, IH5145
• TTL, CMOS Compatible
permits controlling 30V
signals. Power supplies may be
P-P
single-ended from +5V to +34V, or split from ±5V to ±17V.
The analog switches are bilateral, equally matched for AC or
bidirectional signals. The ON resistance variation with analog
signals is quite low over a ±15V analog input range. The three
different devices provide the equivalent of two SPST (DG401),
two SPDT (DG403) or two DPST (DG405) relay switch
contacts with CMOS or TTL level activation. The pinout is
similar, permitting a standard layout to be used, choosing the
switch function as needed.
