Figure 1. Overvoltage Protection Using External Blocking Diodes
__________Applications Information
Operation with Supply Voltages
Other Than ±15V
The DG421/DG423/DG425 switches operate with ±4.5V
to ±20V bipolar supplies or with a +10V to +30V single
supply. In either case, analog signals ranging from V+
to V- can be switched. The
Typical Operating
Characteristics graphs illustrate typical analog-signal
and supply-voltage on-resistance variations. The usual
on-resistance temperature coefficient is 0.5%/°C (typ).
Logic Inputs
These devices operate with a single positive supply or
with bipolar supplies. They maintain TTL compatibility
with supplies anywhere in the ±4.5V to ±20V range as
long as VL = +5V. If VL is connected to V+ or another
supply at voltages other than +5V, the devices will
operate at CMOS-logic-level inputs.
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
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.
