The DG211 is a low cost, CMOS monolithic, Quad SPST analog switch. It can be used in general purpose switching applications for communications, instrumentation, process control and computer peripheral equipment and provides true bi-directional performance in the ON condition and blocks signals to 30VP-Pin the OFF condition.

The DG401 and DG403 monolithic CMOS analog switches have TTL and CMOS compatible digital inputs. These switches feature low analog ON resistance (45Ω) and fast switch time (tON150ns). Low charge injection simplifies sample and hold applications. The improvements in the DG401, DG403 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 controlling 30VP-Psignals. 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) or two SPDT (DG403) 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.

The DG406 and DG407 monolithic CMOS analog multiplexers are drop-in replacements for the popular DG506A and DG507A series devices. They each include an array of sixteen analog switches, a TTL and CMOS compatible digital decode circuit for channel selection, a voltage reference for logic thresholds, and an ENABLE input for device selection when several multiplexers are present. These multiplexers feature lower signal ON-resistance (100Ω) and faster transition time (tTRANS300ns) compared to the DG506A and DG507A. Charge injection has been reduced, simplifying sample and hold applications. The improvements in the DG406 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 controlling 30VP-Psignals when operating with ±15V power supplies. The sixteen 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 DG408 Single 8-Channel, and DG409 Differential 4-Channel monolithic CMOS analog multiplexers are drop-in replacements for the popular DG508A and DG509A series devices. They each include an array of eight analog switches, a TTL/CMOS compatible digital decode circuit for channel selection, a voltage reference for logic thresholds and an ENABLE input for device selection when several multiplexers are present. The DG408 and DG409 feature lower signal ON resistance (100Ω) and faster switch transition time (tTRANS250ns) compared to the DG508A or DG509A. Charge injection has been reduced, simplifying sample and hold applications. The improvements in the DG408 series are made possible by using a high-voltage silicon-gate process. An epitaxial layer prevents the latch-up associated with older CMOS technologies. Power supplies may be single-ended from +5V to +34V, or split from ±5V to ±20V. The analog 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 DG441 and DG442 monolithic CMOS analog switches are drop-in replacements for the popular DG201A and DG202 series devices. They include four independent single pole single throw (SPST) analog switches, TTL and CMOS compatible digital inputs, and a voltage reference for logic thresholds. These switches feature lower analog ON resistance (85Ω) and faster switch time (tON250ns) compared to the DG201A and DG202. Charge injection has been reduced, simplifying sample and hold applications. The improvements in the DG441 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 controlling 40VP-P signals. Power supplies may be single ended from +5V to +34V, symmetrical supplies from ±5V to ±22V or asymmetrical supplies limited to a maximum differential voltage of 44V with a V+ max of 34V or a V- max of -25V. 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 and DG442 are identical, differing only in the polarity of the selection logic.
