NOTES:
3. Lab characterization, room temp, Timing Parameters Matched Stimulus/Loads, Channel-to-Channel Skew < 500ps, 1ns Max by design.
4. Measured across 100pF/1k lump sum load + 15pF PCB/Scope Probe. Cap and Resistor Surface Mount/Stacked ~0.5” from Pin.
5. To Enable LOWSWING, connect LOWSWING to VEE and keep VH < VEE + 5. To disable LOWSWING, connect it to VCC.
6. When VEXT is connected to VEE (External Device Power not used) then the Minimum VCC - VEE is 12V. When VEXT is connected to an external
5.5V supply, then the minimum VCC - VEE voltage is 9V. Recommended VEXT = 5.5V as referenced to VEE.
7. ICC and IEE values are based on static conditions and will increase with pattern rates. ICC and IEE reach 400mA to 500mA at maximum data
rates (provided sufficient device cooling is employed). These currents can be reduced by 1) Reducing the VCC - VEE operating voltage 2)
Utilizing the VEXT option.
8. When using VEXT = 5.5V, current requirements of the VEXT input can approach 100mA at maximum pattern rates.
9. 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.
