Note 2: Operating Ratings indicate conditions for which the device is intended to be functional, but may not meet the guaranteed specific performance limits. For guaranteed specifications and test conditions see the Electrical Characteristics. Note 3: ESD Human Body Model: 100 pF discharged through 1500 X resistor. Note 4: The AC Timing specifications for T OFF are not production tested, and therefore are not specifically guaranteed. Limits are provided for reference purposes only. Smaller load capacitances will have proportionally faster turn-ON and turn-OFF times. Block Diagram TL/H/12317–4
