Unless otherwise specified, testing shall be conducted at worst-case conditions. 2. VIL = –3.0V for pulse widths less than or equal to 20ns. 3. Duration of the short should not exceed one second; only one output may be shorted at a time. 4. Pulse width of WR PROT/PROT FLAG shall be ≥ 80% of STRBD pulse width. |
