The DG1208 and DG1209 are low-leakage, low-charge injection, single 8-channel or dual 4-channel multiplexing switch devices. The DG1208 uses three selection inputs A2, A1, and A0 to determine the switching logic; the DG1209 uses two selection inputs A1 and A0. On both devices, an enable (EN) input is used to enable or disable the device.The low capacitance and low charge injection of the DG1208/DG1209 make them ideal for automatic test equipment systems, data acquisition systems and sample-and- hold systems where low glitch and fast settling time are required.The DG1208/DG1209 are available in 4mm x 4mm 16-lead TQFN or 16-lead TSSOP packages. The devices are specified for operation over the -40°C to +85°C temperature range.ApplicationsAutomatic Test Equipment SystemsData Acquisition SystemsSample-and-Hold SystemsCommunication SystemsAudio and Video Routing

The DG201A and DG211 are normally closed, quad single-pole single-throw (SPST) analog switches. These CMOS switches can be continuously operated with power supplies ranging from ±4.5V to ±18V. Maxim guarantees that these switches will not latch up if the power supplies are disconnected with input signals still connected.Both devices have guaranteed break-before-make switching. The DG201A differs from the DG211 primarily in switching speeds. The DG201A has a maximum turn-off time of 450ns and a maximum turn-on time of 600ns. The DG211 has a maximum turn-off time of 500ns and a maximum turn-on time of 1000ns.Compared to the original manufacturer's products, Maxim's DG201A and DG211 consume significantly lower power making them better suited for portable applications. Maxim has also eliminated the need for the third (VL) power supply that is required for the operation of the original manufacturer's DG211.ApplicationsCommunication SystemsGuidance and Control SystemsHeads-Up DisplaysMilitary RadiosPBX, PABXTest EquipmentWinchester Disk Drives

The DG202/DG212 are normally open, quad single-pole single-throw (SPST) analog switches. These CMOS switches can be continuously operated with power supplies ranging from ±4.5V to ±18V. Maxim guarantees that these switches will not latch up if the power supplies are disconnected with input signals still connected.The DG202/DG212 are similar to the DG201/DG211 except for inverted control inputs. All devices have guaranteed break-before-make switching, as well as essentially constant on-resistance over the analog signal range. All switches conduct current in either direction and add no offset to the output signal.Compared to the original manufacturer's products, Maxim's DG202/DG212 consume very little power, making them better suited for portable applications. Maxim has also eliminated the need for the third logic power supply (VL) that is required for the operation of the original manufacturer's DG212 without sacrificing compatibility.ApplicationsAnalog MultiplexersAutomatic Test EquipmentCommunication SystemsPBX, PABXProgrammable Gain AmplifiersSample/Holds
