NOTES:
2. 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.
3. Supply current specification is valid for loaded drivers when DE = 0V.
4. Applies to peak current. See “Typical Performance Curves” beginning on page 13 for more information.
5. Keep RE = 0 to prevent the device from entering SHDN.
6. The RE signal high time must be short enough (typically <100ns) to prevent the device from entering SHDN.
7. Transceivers are put into shutdown by bringing RE high and DE low. If the inputs are in this state for less than 60ns, the parts are guaranteed
not to enter shutdown. If the inputs are in this state for at least 600ns, the parts are guaranteed to have entered shutdown. See “Low Power
Shutdown Mode” on page 12.
8. Keep RE = VCC, and set the DE signal low time >600ns to ensure that the device enters SHDN.
9. Set the RE signal high time >600ns to ensure that the device enters SHDN.
10. Parts are 100% tested at +25°C. Over-temperature limits established by characterization and are not production tested.
11. See Figure 8 for more information, and for performance over-temperature.
