Notes:
5. Programmable skew on pair #4 is not applicable for the PI6C3Q993A.
6. LL disables outputs if TEST = MID and GND/sOE = HIGH.
7. When pair #4 is set to HH (inverted), GND/sOE disables pair #4 HIGH when VCCQ /PE = HIGH, GND/sOE disables pair #4 LOW
when VCCQ /PE = LOW.
* Outputs of 3Qx and 4Qx are not in phase when 3F1 : 0 = HH and 4F1 : 0 = LL.
Table 4. Absolute Maximum Ratings
Supply Voltage to Ground ...................................... –0.5V to 7.0V
Input Voltage .......................................................... –0.5V to 7.0V
Maximum Power Dissipation at TA = 85°C, PLCC ....... 0.80 watts
QSOP ....... 0.66 watts
TSTG Storage Temperature .................................. –65°C to 150°C
Stresses above those listed under Absolute Maximum Ratings may
cause permanent damage to the device. These ratings arestress speci-
fications only and functional operation of the device at these or any
other conditions above those listed in the operational sections of the
specifications is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect product reliability.
