Limit forward diode current to 0mA maximum. Caution: Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress only rating and operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification is not implied.

The algebraic convention, where the most negative value is a minimum and the most positive is a maximum, is used in this data sheet.. Typical values are for DESIGN AID ONLY, not guaranteed or subject to production testing.. Guaranteed by design. R ΟΝ = R ΟΝ max. R ΟΝ min.. Flatness is defined as the difference between the maximum and minimum value of on-resistance measured.. Leakage parameters are 100% tested at maximum rated hot temperature and guaranteed by correlation at +ºC.. Off Isolation = 0log 10 [V / (V or V )]. See Figure. PS818A 0/9/99

7 Applications Information Positive Supply 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 on first, and then logic inputs. If power-supply sequencing is not possible, add two small signal diodes or two current limiting resistors in series with the supply pins for overvoltage protection (Figure 1). Adding diodes reduces the analog signal range, but low switch resistance and low leakage characteristics are unaffected. V g V- Figure 1. Overvoltage protection is accomplished by using two external blocking diodes or two current limiting resistors. Pericom Semiconductor Corporation 80 Bering Drive San Jose, CA Fax (08) PS818A 0/9/99
