Exceeding these values may cause permanent damage. Functional operation under these conditions is not implied.
Typical figures are at 25C with nominal +5V supply and are for design aid only
Electrical Characteristics are over Recommended Operating Conditions unless otherwise stated.
Typical figures are at 25
°
C with nominal + 5V supplies and are for design aid only.
Note 1: Low Loop current operation depends on value of resistor connected between V
