DC ELECTRICAL CHARACTERISTICS OVER OPERATING RANGE FOR 1.8V
LVTTL
NOTES:
1. See RECOMMENDED OPERATING RANGE table.
2. For 1.8V LVTTL single-ended operation, the RxS pin is MID and REF
3. V
4. V
5. For single-ended operation in differential mode, REF
6. Voltage required to maintain a logic HIGH, single-ended operation in differential mode.
7. Voltage required to maintain a logic LOW, single-ended operation in differential mode.
8. Typical values are at V
9. The reference clock input is capable of HSTL, eHSTL, LVEPECL, 1.8V or 2.5V LVTTL operation independent of the device output. (See Input/Output Selection table.)
10. This value is the worst case minimum V
11. This value is the worst case maximum V
