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 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 performance, but features power dissipa-
tion roughly half of the 100124 to ease system cooling
requirements.
