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. 6. Supply current specification is valid for loaded drivers when DE = 0V. 7. Applies to peak current. See “Typical Performance Curves” starting on page 11 for more information. 8. Because of the shutdown feature, keep RE = 0 to prevent the device from entering SHDN. 9. Because of the shutdown feature, the RE signal high time must be short enough (typically <100ns) to prevent the device from entering SHDN. 10. These IC’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 700ns, the parts are guaranteed to have entered shutdown. See “Low Power Shutdown Mode” on page 11. 11. Keep RE = VCC, and set the DE signal low time >700ns to ensure that the device enters SHDN. 12. Set the RE signal high time >700ns to ensure that the device enters SHDN. 13. This is the part-to-part skew between any two units tested with identical test conditions (Temperature, VCC, etc.). 14. Parts are 100% tested at +25°C. Over-temperature limits established by characterization and are not production tested. Test Circuits and Waveforms FIGURE 1A. VOD AND VOC FIGURE 1B. VOD WITH COMMON MODE LOAD FIGURE 1.
