100324 Low Power Hex TTL-to-ECL Translator

100324
Low Power Hex TTL-to-ECL Translator

General Description

The 100324 is a he x translator, designed to convert TT L
logic levels to 100K ECL logic levels. The inp uts are com­patible with standard or Schottky TTL. A com mon Enable
(E), when LOW, holds all inverting outputs HIGH and holds
all true outputs LOW. The d ifferential 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, over­comes voltage gradients between the TTL and ECL ground
systems. The V

EE

and V

TTL

power may be applied in either
order.
The 100324 is pin and function compatible with the 100124

with similar AC perf ormance, but features po wer dissipa­tion roughly half of the 100124 to ease system cooling
requirements.

Absolute Maximum Ratings(Note 1) Recommended Operating

Conditions

Note 1: The “Absolute Maximum Ratings” are those value s beyond which

the safety of the dev ice cannot b e guaranteed . The device sh ould not be
operated at these limit s. The parametric values defi ned in the Electrical
Characteristics tables are not guaranteed at the absolute maximum rating.
The “Recomm ended O peratin g Cond itions ” table will defin e the condition s
for actual device operation.

Note 2: ESD testing conforms to MIL-STD-883, Method 3015.

Note 3: 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 decreasin g the al l owable syste m opera ti ng ran ge s. Cond it i ons fo r t estin g sho w n in the tabl es are cho­sen to guarantee operation under “worst case” conditions.
