19-3959; Rev 2; 5/06 Quad SPST CMOS Analog Switches Features 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. ♦ Guaranteed ±4.5V to ±18V Operation 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. ♦ Monolithic, Low-Power CMOS Design 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. ♦ No VL Supply Required ♦ Nonlatching with Supplies Turned Off and Input Signals Present ♦ CMOS and TTL Logic Compatible Ordering Information PART TEMP RANGE DG201ACUE 0°C to +70°C 16 TSSOP PIN-PACKAGE DG201ACSE 0°C to +70°C 16 SO DG201ACJ 0°C to +70°C 16 Plastic DIP DG201C/D 0°C to +70°C Dice -40°C to +85°C 16 QFN (5 ✕ 5) DG201AEUE -40°C to +85°C 16 TSSOP DG201ADY -40°C to +85°C 16 SO DG201ADJ -40°C to +85°C 16 Plastic DIP DG201AAK -55°C to +125°C 16 CERDIP Test Equipment DG201ABK DG211CUE -25°C to +85°C 0°C to +70°C 16 CERDIP 16 TSSOP Communications Systems DG211CSE 0°C to +70°C 16 SO PBX, PABX DG211CJ 0°C to +70°C 16 Plastic DIP Guidance and Control Systems DG211C/D 0°C to +70°C Dice Head Up Displays DG211EGE -40°C to +85°C Military Radios DG211EUE DG211DY -40°C to +85°C -40°C to +85°C DG211DJ -40°C to +85°C Applications Winchester Disk Drives Pin Configurations continued at end of data sheet.

In either case, source-to-body diodes can be forward biased and conduct current from the signal source. If this current is required to be kept to low (µA) levels then the addition of external protection diodes is recommended. Pin Configurations (continued) To provide protection for overvoltages up to 20V above the supplies, a 1N4001 or 1N914 type diode should be placed in series with the positive and negative supplies as shown in Figure 2. The addition of these diodes will reduce the analog signal range to 1V below the positive supply and 1V above the negative supply.
