NOTES:
6. Lab characterization, room temp, Timing Parameters Matched Stimulus/Loads, Channel-to-Channel Skew < 500ps, 1ns Max by design.
7. Measured across 100pF/1k lump sum load + 15pF PCB/Scope Probe. Cap and Resistor Surface Mount/Stacked ~0.5” from Pin.
8. To Enable LOWSWING, connect LOWSWING to V_EE and keep VH < V_EE + 5. To disable LOWSWING, connect it to V_CC.
9. When V_EXT is connected to V_EE (External Device Power not used) then the Minimum V_CC - V_EE is 12V. When V_EXT is connected to an external 5.5V
supply, then the minimum V_CC - V_EE voltage is 9V. Recommended V_EXT = 5.5V as referenced to V_EE.
10. I_CC and I_EE values are based on static conditions and will increase with pattern rates. I_CC and I_EE reach 400mA to 500mA at maximum data rates
(provided sufficient device cooling is employed). These currents can be reduced by 1) Reducing the V_CC - V_EE operating voltage 2) Utilizing the V_EXT
option.
11. When using V_EXT = 5.5V, current requirements of the V_EXT input can approach 100mA at maximum pattern rates.
12. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by characterization
and are not production tested.When using V_EXT = 5.5V, current requirements of the V_EXT input can approach 100mA at maximum pattern rates.
13. Device temperature is closely tied to data-rates, driver loads and overall pin activity. Review “Power Dissipation Considerations” on page 9 for more
information.
