1 191362; Rev 2; 6/4 Quad, SPST Analog Switch General Description The quad analog switch features onresistance matching (4Ω max) between switches and guarantees onresistance flatness over the signal range (9Ω max). This low onresistance switch conducts equally well in either direction. It guarantees low charge injection (1pC max), low power consumption (35µW max), and an electrostatic discharge (ESD) tolerance of 2V minimum per Method The new design offers lower offleakage current over temperature (less than 5nA at +85 C). The quad, singlepole/singlethrow (SPST) analog switch has two normally closed switches and two normally open switches. Switching times are less than 25ns for ton and less than 7ns for toff. Operation is from a single +4.5V to +4V supply or bipolar ±4.5V to ±2V supplies.

Pin Description Applications Information General Operation 1) Switches are open when power is off. 2),, and should not exceed or, even with the power off. 3) Switch leakage is from each analog switch terminal to or, not to other switch terminals. Operation with Supply Voltages Other than ±15V Using supply voltages less than ±15V will reduce the analog signal range. The operates with ±4.5V to ±2V bipolar supplies or with a +4.5V to +4V single supply; connect to when operating with a single supply. Also, all device types can operate with unbalanced supplies such as +24V and 5V. must be connected to to be TTL compatible, or to for CMOSlogic level inputs. The Typical Operating Characteristics graphs show typical onresistance with ±2V, ±15V, ±1V, and ±5V supplies. (Switching times increase by a factor of two or more for operation at ±5V.) Overvoltage Protection Proper powersupply 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 on first, followed by,, and logic inputs. If powersupply sequencing is not possible, add two small, external signal diodes in series with supply pins for overvoltage protection (Figure 1). Adding diodes reduces the analog signal range to 1V below and 1V above, but low switch resistance and low leakage characteristics are unaffected. Device operation is unchanged, and the difference between and should not exceed +44V. V g S Figure 1. Overvoltage Protection Using External Blocking Diodes D 6
