The MAX317/MAX318/MAX319 are fabricated withMaxim’s new improved silicon-gate process. Designimprovements guarantee extremely low charge injec-tion (10pC), low power consumption (35µW), and elec-trostatic discharge (ESD) greater than ±2000V. The44V maximum breakdown voltage allows rail-to-rail ana-log signal handling capability.

__________Applications InformationOperation with Supply VoltagesOther Than ±15VThe main limitation of supply voltages other than ±15Vis analog signal range reduction. The MAX317/MAX318/MAX319 switches operate with bipolar sup-plies of ±5V to ±20V. Typical Operating Characteristicsgraphs show typical on resistance for ±15V, ±10V, and±5V supplies. Switching times increase by a factor oftwo or more for operation at ±5V. TheMAX317/MAX318/MAX319 can operate from unipolarsupplies of +10V to +30V. Both parts can also operatefrom unbalanced supplies such as +24V and -5V.
Connect V- to 0V when operating with a single supply.This means that VL must be connected to +5V to beTTL compatible, or to V+ for CMOS logic input levels.
adding two small signal diodes in series with the sup-ply pins (Figure 1). Adding the diodes reduces theanalog signal range to 1V below V+ and 1V below V-,but low switch resistance and low leakage characteris-tics are unaffected. Device operation is unchanged,and the difference between V+ to V- should not exceed+44V.
V+V+NO_COM_Overvoltage ProtectionProper power-supply sequencing is recommended forall CMOS devices. It is important not to exceed theabsolute maximum ratings because stresses beyondthe listed ratings may cause permanent damage to thedevices. Always sequence V+ on first, followed by VL,V-, and logic inputs. If power-supply sequencing is notpossible, protect the devices from overvoltage by
