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 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
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 dissipation
roughly half of the 100124 to ease system cooling require-
ments.

Note 3: F100K 300 Series cold temperature testing is performed by temperature soaking (to guarantee junction temperature equals −55˚C), then testing immediately
without allowing for the junction temperature to stabilize due to heat dissipation after power-up. This provides “cold start” specs which can be considered a worst case
condition at cold temperatures.
Note 4: Screen tested 100% on each device at −55˚C, +25˚C, and +125˚C, Subgroups 1, 2, 3, 7, and 8.
Note 5: Sample tested (Method 5005, Table I) on each manufactured lot at −55˚C, +25˚C, and +125˚C, Subgroups A1, 2, 3, 7, and 8.
Note 6: Guaranteed by applying specified input condition and testing VOH/VOL.
