These switches conduct equally well in either direction and guarantee low charge injection, low power consumption, and an ESD tolerance of 2000V minimum per Method 3015.7. The new design offers low off-leakage current over temperature (less than 5nA at +85C). The DG417/DG418 are single-pole/single-throw (SPST) switches. The DG417 is normally closed, and the DG418 is normally open. The DG419 is singlepole/double-throw (SPDT) with one normally closed switch and one normally open switch. Switching times are less than 175ns max for tON and less than 145ns max for tOFF. Operation is from a single +10V to +30V supply, or bipolar 4.5V to 20V supplies. The improved DG417/DG418/DG419 are fabricated with a 44V silicon-gate process.

Limit forward current to maximum current ratings. Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

The algebraic convention where the most negative value is a minimum and the most positive value a maximum is used in this data sheet. Note 3: Guaranteed by design. Note 4: On-resistance match between channels and flatness is guaranteed only with bipolar-supply operation. Flatness is defined as the difference between the maximum and the minimum value of on-resistance as measured at the extremes of the specified analog range. Note 5: Leakage parameters IS(OFF), ID(OFF), and ID(ON) are 100% tested at the maximum rated hot temperature and guaranteed by correlation at +25C.

The DG417/DG418/DG419 switches operate with 4.5V to 20V bipolar supplies or with a +10V to +30V single supply; connect V- to 0V when operating with a single supply. Also, all device types can operate with unbalanced supplies, such as +24V and -5V. VL must be connected to +5V to be TTL compatible, or to V+ for CMOS-logic level inputs. The Typical Operating Characteristics graphs show typical on-resistance with 20V, 15V, 10V, and 5V supplies. (Switching times increase by a factor of two or more for operation at 5V.) Overvoltage Protection Proper power-supply sequencing is recommended for all CMOS devices. Do not exceed the absolute maximum ratings because stresses beyond the listed ratings may cause permanent damage to the devices. Always sequence V+ on first, followed by VL, V-, and logic inputs. If power-supply sequencing is not possible, add two small, external signal diodes in series with the supply pins for overvoltage protection (Figure 1). 6 S D Vg DG41_ V- Figure 1. Overvoltage Protection Using External Blocking Diodes Adding diodes reduces the analog signal range to 1V below V+ and 1V above V-, without affecting low switch resistance and low leakage characteristics. Device operation is unchanged, and the difference between V+ and V- should not exceed +44V. _______________________________________________________________________________________ Improved, SPST/SPDT Analog Switches LOGIC INPUT t R < 20ns t F < 20ns +3V 50% SWITCH INPUT 0V +5V +15V VL V+ D DG417 DG418 IN SWITCH OUTPUT 0V 0.9 x VOUT 0.9 x VOUT t ON GND LOGIC INPUT VOUT RL 300 t OFF VOUT SWITCH OUTPUT S CL 35pF V- -15V CL INCLUDES FIXTURE AND STRAY CAPACITANCE.
