TI DG403EJ

The DG401, DG403 and DG405 monolithic CMOS analog switches have TTL and CMOS compatibiedigital inputs. These switches feature low analog ON resistance (<35Ω) and fast switch time (ton<150ns). Low charge injection simplifies sample and hold applications. 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 permits controling 30Vp-p signals. Power supplies may be 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.
