The MAX351 has four normally closed (NC), and the MAX352 has four normally open (NO) switches. The MAX353 has two NO and two NC switches. 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 MAX351/MAX352/MAX353 are fabricated with Maxim's new improved 44V 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.

The MAX351/ MAX352/MAX353 operate with 5V to 20V bipolar supplies. The Typical Operating Characteristics graphs show typical on resistance (RON) 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 maximum ratings because stresses beyond the listed ratings 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 Vshould not exceed +44V. V+ V+ NO_ COM_ Vg V- V- Figure 1.
