The single-pole singlethrow (SPST) MAX317 is normally closed (NC), the SPST MAX318 is normally open (NO), and the singlepole double-throw (SPDT) MAX319 has one normally open and one normally closed switch. All three parts offer low on resistance (less than 35), guaranteed to match within 2 between channels and to remain flat over the analog signal range (3 max). They also offer low leakage (less than 250pA at +25C and less than 6nA at +85C) and fast switching (turn-on time less than 175ns and turn-off time less than 145ns). The MAX317/MAX318/MAX319 are fabricated with Maxim's new improved silicon-gate process. Design improvements guarantee extremely low charge injection (10pC), low power consumption (35W), and electrostatic discharge (ESD) greater than 2000V. The 44V maximum breakdown voltage allows rail-to-rail analog signal handling capability.

The MAX317/ MAX318/MAX319 switches operate with bipolar supplies of 5V to 20V. Typical Operating Characteristics graphs show typical on resistance for 15V, 10V, and 5V supplies. Switching times increase by a factor of two or more for operation at 5V. The MAX317/MAX318/MAX319 can operate from unipolar supplies of +10V to +30V. Both parts can also operate from 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 be TTL compatible, or to V+ for CMOS logic input levels. Overvoltage Protection Proper power-supply sequencing is recommended for all CMOS devices. It is important not to exceed the absolute maximum ratings because stresses beyond the listed ratings may cause permanent damage to the devices. Always sequence V+ on first, followed by VL, V-, and logic inputs. If power-supply sequencing is not possible, protect the devices from overvoltage by 6 adding two small signal diodes in series with the supply pins (Figure 1). Adding the 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. V+ V+ NO_ COM_ Vg V- V- Figure 1.
