Precision, Quad, SPDT, CMOS Analog Switch
_______________General Description
The MAX333A is a precision, quad, single-pole double-
throw (SPDT) analog switch. The four independent
switches operate with bipolar supplies ranging from
±4.5V to ±20V, or with a single-ended supply between
+10V and +30V. The MAX333A offers low on resistance
(less than 35Ω), guaranteed to match within 2Ωbetween
channels and to remain flat over the analog signal range
(Δ3Ωmax). It also offers break-before-make switching
(10ns typical), with turn-off times less than 145ns and
turn-on times less than 175ns. The MAX333A is ideal for
portable operation since quiescent current runs less
than 50μA with all inputs high or low.
This monolithic, quad switch is fabricated with Maxim’s
new improved silicon-gate process. Design improvements
guarantee extremely low charge injection (10pC), low
power consumption (3.75mW), and electrostatic discharge
(ESD) greater than 2000V.
Logic inputs are TTL and CMOS compatible and guaranteed
over a +0.8V to +2.4V range—regardless of supply voltage.
Logic inputs and switched analog signals can range any-
where between the supply voltages without damage.

ELECTRICAL CHARACTERISTICS—Dual Supplies

(GND = 0V, V+ = +15V, V- = -15V, TA= +25°C, unless otherwise noted.)
Note 1:
Device mounted with all leads soldered to PC board.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and function-
al operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure
to absolute maximum rating conditions for extended periods may affect device reliability.

ELECTRICAL CHARACTERISTICS—Single Supply

(GND = 0V, V+ = +12V, V- = 0V, TA = +25°C, unless otherwise noted.)
Note 2:
The algebraic convention, whereby the most negative value is a minimum and the most positive is a maximum, is used in
this data sheet.
Note 3:
Typical values are for design aid only, not guaranteed or subject to production testing.
Note 4:
On resistance match between channels and flatness are guaranteed only with bipolar-supply operation.

__________Applications Information
Operation with Supply Voltages
Other than ±15Vo
The main limitation of supply voltages other than ±15V is
a reduction in the analog signal range. The MAX333A
operates with ±5V to ±20V bipolar supplies. The
Typical Operating Characteristicsand graphs show typ-
ical on resistance for ±15V, ±10V, ±5 supplies.
Switching times increase by a factor of two or more for
±5V operation. The MAX333A can operate from +10V
to +24V unipolar supplies. It can be powered from a
single +10V to +24V supply, as well as from unbalanced
supplies such as +24V and -5V. Connect V- to 0V when
operating with a single supply.
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 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, add two small signal diodes in series with the
supply 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.
