max351/max352/max353 __________applications information operation with supplies other than 15v the main limitation of supply voltages other than 15v is reduced analog-signal range. the max351/ max352/max353 operate with 5v to 20v bipolar supplies. the typical operating characteristics graphs show typical on resistance (r on ) for 15v, 10v, and 5v supplies. (switching times increase by a factor of two or more for operation at 5v.) the max351/ max352/max353 can operate from +10v to +30v unipolar supplies. each device can also be powered from unbalanced supplies such as +24v and -5v. connect v- to 0v when operating with a single supply. vl must be connected to +5v to be ttl compatible or to v+ for cmos-logic input levels. 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+ 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 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 operation is unchanged, and the difference between v+ to v- should not exceed +44v. precision, quad, spst analog switches 6 _______________________________________________________________________________________ ______________________________________________________________pin description v+ com_ v- no_ v g v+ v- figure 1. overvoltage protection using external blocking diodes pin dip/so qfn name function 1, 16, 9, 8 15, 14, 7, 6 in1 n4 logic control input 2, 15, 10, 7 16, 13, 8, 5 com1 com4 analog switch common terminal 3, 15, 11, 6 1, 12, 9, 4 no or nc analog switch no or nc terminal 4 2 v- negative-supply voltage input 5 3 gnd ground 12 10 v l logic supply voltage 13 11 v+ positive-supply voltage input connected to substrate
