Precision, Quad, SPST Analog Switches
General Description
Features
The MAX391/MAX392/MAX393 are precision, quad,
single-pole/single-throw (SPST) analog switches
designed to operate at +3V, +5V, or 5Vꢀ The MAX391
has four normally closed (NC) switches, and the
MAX392 has four normally open (NO) switchesꢀ The
MAX393 has two NO and two NC switchesꢀ All three
devices offer low leakage (100pA max) and fast switch-
ꢀ Low On-Resistance, 20Ω Typical
ꢀ Guaranteed On-Resistance Match Between
Channels, <2Ω
ꢀ Guaranteed On-Resistance Flatness Over Signal
Range, 4Ω Max
ꢀ Guaranteed Charge Injection, <5pC
ing speeds (t
≤ 130ns, t
≤ 75ns)ꢀ Power con-

ꢀ Improved Leakage Over Temperature,
sumption is just 1µW—ideal for battery-operated equip-
mentꢀ All devices operate from a single +3V to +15V
supply or from dual 3ꢀ0V to ꢁV suppliesꢀ
<2.5nA at +85°C
ꢀ Electrostatic Discharge >2000V per Method

With 5V supplies, the MAX391/MAX392/MAX393 offer
ꢀ Single-Supply Operation (+3V to +15V)
guaranteed 2Ω max channel-to-channel matching, 30Ω

over the specified rangeꢀ
ꢀ Low Power Consumption, <1µW
ꢀ TTL/CMOS-Logic Compatible
These switches are also fully specified for single +5V
operation, with 2Ω max R
match, 60Ω max R
ON, and
ON
6Ω max flatnessꢀ
Ordering Information
These low-voltage switches also offer 5pC max charge
injection, and ESD protection is greater than 2000V, per
method 3015ꢀ7ꢀ

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.

Overvoltage Protection
Proper power-supply sequencing is recommended for
all CMOS devicesꢀ Do not exceed the absolute maxi-
mum ratings, because stresses beyond the listed rat-
ings may cause permanent damage to the devicesꢀ
Always sequence V+ on first, followed by V-, and then
logic inputsꢀ If power-supply sequencing is not possi-
ble, add two small signal diodes in series with 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 characteristics are unaffectedꢀ Device opera-
tion is unchanged, and the difference between V+ and
V- should not exceed 17Vꢀ
