AC DIFFERENTIAL INPUT SPECIFICATIONS
HSTL/eHSTL/1.8V LVTTL/2.5V LVTTL
LVEPECL
NOTES:
1. For differential input mode, RxS is tied to GND.
2. Both differential input signals should not be driven to the same level simultaneously. The input will not change state until the inputs have crossed and the voltage range defined
3. Differential mode only. V
4. For single-ended operation, REF
5. Voltage required to switch to a logic HIGH, single-ended operation only.
6. Voltage required to switch to a logic LOW, single-ended operation only.
