The four independent switches operate with bipolar supplies ranging from ±4.5V to ±20V, or with a single-ended supply between +10V and +30V. The MAX333A offers low on resistance (less than 35Ω), guaranteed to match within 2Ω between channels and to remain flat over the analog signal range (∆3Ω max). It also offers break-before-make switching (10ns typical), with turn-off times less than 145ns and turn-on times less than 175ns. The MAX333A is ideal for portable operation since quiescent current runs less than 50µA with all inputs high or low.

Not Internally Connected 16 V+ Normally Open Switches Common Switch Poles Normally Closed Switches Negative Power Supply 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, add 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. Positive Power Supply V+ __________Applications Information Operation with Supply Voltages Other than ±15Vo The main limitation of supply voltages other than ±15V is a reduction in the analog signal range. The MAX333A operates with ±5V to ±20V bipolar supplies. The Typical Operating Characteristics and graphs show typical on resistance for ±15V, ±10V, ±5 supplies. Switching times increase by a factor of two or more for ±5V operation. The MAX333A can operate from +10V to +24V unipolar supplies. It can be powered from a single +10V to +24V supply, as well as from unbalanced supplies such as +24V and -5V. Connect V- to 0V when operating with a single supply. NO_ ( OR NC_) COM_ Vg V- Figure 1.
