_______________General DescriptionThe MAX317/MAX318/MAX319 are precision, CMOS,
monolithic analog switches. The single-pole single-
throw (SPST) MAX317 is normally closed (NC), the
SPST MAX318 is normally open (NO), and the single-
pole double-throw (SPDT) MAX319 has one normally
open and one normally closed switch. All three parts
offer low on resistance (less than 35Ω), guaranteed to
match within 2Ωbetween channels and to remain flat
over the analog signal range (Δ3Ωmax). They also
offer low leakage (less than 250pA at +25°C and less
than 6nA at +85°C) and fast switching (turn-on time
less than 175ns and turn-off time less than 145ns).
The MAX317/MAX318/MAX319 are fabricated with
Maxim’s new improved silicon-gate process. Design
improvements guarantee extremely low charge injec-
tion (10pC), low power consumption (35µW), and elec-
trostatic discharge (ESD) greater than ±2000V. The
44V maximum breakdown voltage allows rail-to-rail ana-
log signal handling capability.

Operation with Supply Voltages
Other Than ±15VThe main limitation of supply voltages other than ±15V
is analog signal range reduction. The MAX317/
MAX318/MAX319 switches operate with bipolar sup-
plies of ±5V to ±20V. Typical Operating Characteristics
graphs show typical on resistance for ±15V, ±10V, and
±5V supplies. Switching times increase by a factor of
two or more for operation at ±5V. The
MAX317/MAX318/MAX319 can operate from unipolar
supplies of +10V to +30V. Both parts can also operate
from unbalanced supplies such as +24V and -5V.
Connect V- to 0V when operating with a single supply.
This means that VL must be connected to +5V to be
TTL compatible, or to V+ for CMOS logic input levels.
Overvoltage ProtectionProper power-supply sequencing is recommended for
all CMOS devices. It is important not to 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, protect the devices from overvoltage by
adding two small signal diodes in series with the sup-
ply pins (Figure 1). Adding the diodes reduces the
analog signal range to 1V below V+ and 1V below V-,
but low switch resistance and low leakage characteris-
tics are unaffected. Device operation is unchanged,
and the difference between V+ to V- should not exceed
+44V.
