__________Applications Information
Operation with Supply Voltages
Other than ±15V
The MAX301/MAX303/MAX305 switches operate with
±4.5V to ±20V bipolar supplies and a +10V to +30V sin-
gle supply. In either case, analog signals ranging from V+
to V- can be switched. The
Typical Operating
Characteristics graphs show the typical on-resistance
variation with analog signal and supply voltage. The usual
on-resistance temperature coefficent is 0.5%/°C (typ).
Logic Inputs
The MAX301/MAX303/MAX305 operate with a single pos-
itive supply or with bipolar supplies. The devices 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. It is important not to exceed the absolute
maximum 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 possible,
add two small 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
below V-, but low switch resistance and low leakage char-
acteristics are unaffected. Device operation is
unchanged, and the difference between V+ to V- should
not exceed +44V.
