Ordering Information

_______________General Description

The MAX391/MAX392/MAX393 are precision, quad,single-pole/single-throw (SPST) analog switches designed to operate at +3V, +5V, or ±5V. The MAX391has four normally closed (NC) switches, and the MAX392 has four normally open (NO) switches. The MAX393 has two NO and two NC switches. All three devices offer low leakage (100pA max) and fast switch-ing speeds (t ON ≤130ns, t OFF ≤75ns). Power con-sumption is just 1μW—ideal for battery-operated equip-ment. All devices operate from a single +3V to +15V supply or from dual ±3.0V to ±8V supplies.

With ±5V supplies, the MAX391/MAX392/MAX393 offer guaranteed 2Ωmax channel-to-channel matching, 30Ωmax on-resistance (R ON ), and 4Ωmax R ON flatness over the specified range.

These switches are also fully specified for single +5V operation, with 2Ωmax R ON match, 60Ωmax R ON, and 6Ωmax flatness.

These low-voltage switches also offer 5pC max charge injection, and ESD protection is greater than 2000V, per method 3015.7.

ELECTRICAL CHARACTERISTICS—Dual Supplies

(V+ = +5V ±10%, V- = -5V ±10%, GND = 0V, V INH = 2.4V, V INL = 0.8V, T A = T MIN to T MAX , unless otherwise noted.)

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.

Note 1:

Signals on NC_, NO_, COM_, or IN_ exceeding V+ or V- are clamped by internal diodes. Limit forward diode current to maxi-mum current rating.

__________Applications Information

Overvoltage Protection

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, followed by V-, and then logic inputs. 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 unaffected. Device opera-tion is unchanged, and the difference between V+ and V- should not exceed 17V.
