NOTES:
7. All currents into device pins are positive; all currents out of device pins are negative. All voltages are referenced to device ground unless
otherwise specified.
8. Applies to peak current. See “Typical Performance Curves” on page 12 for more information.
9. tSKPP is the magnitude of the difference in propagation delays of the specified terminals of two units tested with identical test conditions (VCC,
temperature, etc.).
10. If the driver enable function isn’t needed, connect DE to VCC (or VL) through a 1kΩ to 3kΩ resistor.
11. Parts are 100% tested at +25°C. Over-temperature limits established by characterization and are not production tested.
12. Due to the high short circuit current at VCC > 3.6V, the outputs must not be shorted outside the range of GND to VCC or damage may occur. To
prevent excessive power dissipation that may damage the output, the short circuit current should be limited to
≤ 300mA during testing. It is best
to use an external resistor for this purpose, since the current limiting on the VO supply may respond too slowly to protect the output.
13. Typicals are measured at VCC = 3.3V for parameters specified with 3V ≤ VCC ≤ 3.6V, and are measured at VCC = 5V for parameters specified
with 4.5V
≤ V
CC ≤ 5.5V. If VCC isn’t specified, then a single “TYP” entry applies to both VCC = 3.3V and 5V, and two entries separated by a
comma refer to VCC = 3.3V and 5V, respectively.
