NOTE:
1. Permanent device damage may occur if ABSOLUTE MAXIMUM RATINGS are exceeded. This is a stress rating only and functional operation is not implied
at conditions other than those detailed in the operational sections of this data sheet. Exposure to ABSOLUTE MAXIMUM RATING conditions for extended
periods may affect device reliability.

DC ELECTRICAL CHARACTERISTICS(1), (2), (3)
NOTES:
1. To calculate total power supply current into the VCC pins: ICC = (n * IOUT); where n = number of ECL output pins used (ie, terminated).
2. To calculate total device power dissipation; PD = [IEE * (VCC - VEE)] + [n * IOUT * 1.33](3).
3. Average ECL output voltage is calculated as VOAVG = (VOH(max) + VOH(min) + VOL(max) + VOL(min)) /4 = 1.33V.

NOTES:
1. Equilibrium temperature
2. Forcing one input at a time. Apply VIH (max) or VIL (min) to all other inputs.
