Note 2: Typical values are for design aid only, are not guaranteed, and are not subject to production testing. 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.

__________Applications Information

Operation with Supply Voltages

Other than ±15V

Using supply voltages other than ±15V reduces the

analog signal range. The DG417/DG418/DG419 switch-

es 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 com-

patible, or to V+ for CMOS-logic level inputs. The

Typical Operating Characteristics

graphs show typical

on-resistance with ±20V, ±15V, ±10V, and ±5V sup-

plies. (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 maxi-

mum ratings because stresses beyond the listed rat-

ings 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 possi-

ble, add two small, external signal diodes in series with

the supply pins for overvoltage protection (Figure 1).

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.
