Notes:

1. Programmable skew on pair #4 is not applicable

for the PI6C993.

2. LL disables outputs if TEST = MID and GND/

sOE = HIGH.

3. 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

Table 4. Absolute Maximum Ratings

Supply Voltage to ground ........................................................ –0.5Vto7.0V

DC input Voltage VI .................................................................... –0.5V to VCC + 0.5V

Maximum Power Dissipation at TA = 85°C, PLCC ......................... 0.80 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 are

stress specifications 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 ex-

tended periods may affect product reliability.
