低功耗Hex TTL-to-ECL翻译
一般描述
The 100324 is a hex translator, designed to convert TTL
logic levels to 100K ECL logic levels. The inputs are compat-
ible 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 compen-
sated 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 performance, but features power dissipation
roughly half of the 100124 to ease system cooling require-
ments.
