SWITCHING CHARACTERISTICS

The q denotes specifications which apply over the full operating

temperature range.

Note 1: Absolute Maximum Ratings are those values beyond which the life

of a device may be impaired.

Note 2: All currents into the device pins are positive; all currents out of the

device pins are negative.

Note 3: All typicals are given for VDD = 5V, TA = 25°C.

Note 4: Guaranteed by design, but not tested.

Note 5: Short-circuit current does not represent output drive capability.

When the output detects a short-circuit condition, output drive current is

significantly reduced (from hundreds of mA to 20mA max) until the short

is removed.
