5 / 11 page 5 Time to Shutdown tSHDN (Note 7) Full 80 190 300 ns Receiver Enable from Shutdown to Output High tZH(SHDN) RL = 1kΩ, CL = 15pF, SW = GND (Figure 5), (Notes 7, 9) Full - 240 400 ns Receiver Enable from Shutdown to Output Low tZL(SHDN) RL = 1kΩ, CL = 15pF, SW = VCC (Figure 5), (Notes 7, 9) Full - 240 400 ns 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” for more information. 5. When testing this parameter, keep RE = 0 to prevent the device from entering SHDN. 6. When testing this parameter, the RE signal high time must be short enough (typically <100ns) to prevent the device from entering SHDN. 7. The ISL43485 is put into shutdown by bringing RE high and DE low. If the inputs are in this state for less than 80ns, the parts are guaranteed not to enter shutdown. If the inputs are in this state for at least 300ns, the parts are guaranteed to have entered shutdown. See “Low-Power Shutdown Mode” section. 8. Keep RE = VCC, and set the DE signal low time >300ns to ensure that the device enters SHDN. 9. Set the RE signal high time >300ns to ensure that the device enters SHDN.
