Using supply voltages other than ±15V will reduce the
analog signal range. The MAX306/MAX307 switches
operate with ±4.5V to ±20V bipolar supplies or with a
+4.5V to +30V single supply; connect V- to GND when
operating with a single supply. Also, both device types
can operate with unbalanced supplies such as +24V
and -5V. 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.)
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, then V-, followed by either
the logic inputs, NO, or COM. If power-supply
sequencing is not possible, add two small signal
diodes in series with supply pins for overvoltage pro-
tection (Figure 1). Adding diodes reduces the analog

signal range to 1V above V+ and 1V below V-, but low
switch resistance and low leakage characteristics are
unaffected. Device operation is unchanged, and the
difference between V+ and V- should not exceed +44V.
