100324
Low Power Hex TTL-to-ECL Translator
General Description
The 100324 is a hex translator, designed to convert TTL
logic levels to 100K ECL logic levels. The inputs are com-
patible with standard or Schottky TTL. A common Enable
(E), when LOW, holds all inverting outputs HIGH and holds
all true outputs LOW. The differential outputs allow each
circuit to be used as an inverting/non-inverting translator, or
as a differential line driver. The output levels are voltage
compensated over the full −4.2V to −5.7V range.
When the circuit is used in the differential mode, the
100324, due to its high common mode rejection, over-
comes voltage gradients between the TTL and ECL ground
systems. The VEE and VTTL power may be applied in either
order.
The 100324 is pin and function compatible with the 100124
with similar AC performance, but features power dissipa-
tion roughly half of the 100124 to ease system cooling
requirements.

Note 5: The specified limits represent the “worst case” value for the parameter. Since these values normally occur at the temperature extremes, additional
noise immunity and guardbanding can be achieved by decreasing the allowable system operating ranges. Conditions for testing shown in the tables are cho-
sen to guarantee operation under “worst case” conditions.
