Low Power Hex TTL-to-ECL Translator
100324 Low Power Hex TTL-to-ECL Translator
July 1988
Revised August 2000
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 level s are voltage
compensated over the full
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
order.
The 100324 is pin and function compatible with the 100124
with similar AC p erformance, but features power dissipation roughly half of the 100124 to ease system cooling
requirements.

Note 1: The “Absolute Maximum Ratings” are those value s beyond which
the safety of the d evice 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.
