MAX4564
Low-Voltage, Dual-Supply,
SPDT Analog Switch with Enable
General Description
Features
o 60Ω max (40Ω, typ) On-Resistance (RON)
The MAX4564 is a low-voltage, dual-supply, singlepole/double-throw (SPDT) analog switch designed to
operate from dual ±1.8V to ±6V or single +1.8V to
+12V supplies. The low on-resistance (RON = 40Ω at
±5V) and low power consumption (5µW) make this part
ideal for audio, video, and battery-powered applications. This switch offers low leakage currents (1nA
max) and fast switching speeds (tON = 60ns and tOFF
= 40ns at ±5V, max).
The MAX4564 is available in 8-pin SOT23 and µMAX®
packages.
o Low Charge Injection: 3pC (typ)

Note 1: Signals on NO, NC, COM, IN, or EN exceeding V+ or V- are clamped by internal diodes. Limit forward-diode current to maximum
current rating.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
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.

The algebraic convention is used in this data sheet; the most negative value is shown in the minimum column.
SOT-packaged products are 100% tested at +25°C and guaranteed by design at the full-rated temperature.
∆RON = RON(MAX) - RON(MIN).
Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the
specified analog signal ranges.
Note 6: Guaranteed by design.

Detailed Description
Test Circuits/
Timing Diagrams
The MAX4564 is a dual-supply SPDT CMOS analog
switch. The MAX4564 has break-before-make switching. The CMOS switch construction provides Rail-toRail ® signal handling while consuming virtually no
power. Each of the two switches is independently controlled by a TTL/CMOS-level-compatible digital input.

Applications Information
MAX4564
Overvoltage Protection
Do not exceed the absolute maximum ratings because
stresses beyond the listed ratings may cause permanent damage to the device. Proper power-supply
sequencing is recommended for all CMOS devices.
Always sequence V+ on first, then V-, followed by the
logic inputs NO, NC, or COM. If power-supply
sequencing is not possible, add two small-signal
diodes (D1, D2) in series with supply pins. Adding
diodes reduces the analog signal range to one diode
drop below V+ and one diode drop above V-, but does
not affect the device’s low switch resistance and low
leakage characteristics.
