Absolute Maximum Ratings(Note 5) Recommended Operating
Conditions
Note 5: The “Absolute Maximum Ratings” are thos e values bey ond which
the saf ety of the device cannot be gu aranteed. Th e device shoul d not be
operated at these limits. The parametric values defined in the Electrical
Characteristics tables are not guaranteed at the absolute maximum rating.
The “R ecomm ended Oper ating Co ndition s” table will def ine the condit ions
for actu al device operation.
Note 6: ESD te s ti ng c onforms t o M I L-STD-8 83, Meth od 3015.
Note 7: Eith er v oltage lim it or c urrent limit is sufficien t to prot ect inputs .

TTL-to-ECL DC Electrical Characteristics (Note 8)
VEE = −4.2V to −5.7V, GND = 0V, TC = 0°C to +85°C, VTTL = +4.5V to +5.5V
Note 8: The specified limits represe nt the “worst case” value for the parameter. Since these values normally occur at the temperature extremes, additional
noise immunity and guard bandi ng can be achi ev ed by decre asin g t he all owable syste m op era ti ng r anges. Co ndi ti ons fo r t est ing shown in the ta ble s are cho-
sen to guarant ee opera t ion under “worst case” conditions .
