NOTES:
4. 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.
5. Supply current specification is valid for loaded drivers when DE = 0V.
6. Applies to peak current. See “Typical Performance Curves” for more information.
7. Keep RE = 0 to prevent the device from entering SHDN.
8. The RE signal high time must be short enough (typically <100ns) to prevent the device from entering SHDN.
9.
Transceiver
s 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” section.
10. Keep RE = VCC, and set the DE signal low time >600ns to ensure that the device enters SHDN.
11. Set the RE signal high time >600ns to ensure that the device enters SHDN.
12. Guaranteed by characterization but not tested.
