AC Information (continued)
Notes:
1. 10EL circuits are designed to meet the DC specifications shown in the table after thermal equilibrium
has been established. The circuit is in a test socket or mounted on a printed circuit board and
transverse airflow greater than 500 lfpm is maintained. Outputs are terminated through a 50W
resistor to VCC - 2.0V except where otherwise specified on the individual data sheets.
2. 100K circuits are designed to meet the DC specifications shown in the table where transverse airflow
greater than 500 lfpm is maintained.
3. Minimum input swing for which AC parameters are guaranteed.
4. CMR range is referenced to the most positive side of the differential input signal. Normal operation
is obtained if the high level falls within the specified range and the peak-to-peak voltage lies between
VPP
and 1V. The lower end of the CMR range varies 1:1 with VEE and is equal to VEE + 1.7V.
(min)
5. Voltages referenced to VCC = 0V.
6. For standard ECL DC specifications, refer to the ECL Logic Family Standard DC Specifications Data
Sheet.
7. For part ordering description, see HPP Part Ordering Information Data Sheet.
