100325

Low Power Hex ECL-to-TTL Translator

General Description

The 100325 is a hex translator for converting F100K logic

levels to TTL logic levels. Differential inputs allow each circuit

to be used as an inverting, non-inverting or differential re-

ceiver. An internal reference voltage generator provides V

BB

for single-ended operation, or for use in Schmitt trigger appli-

cations. All inputs have 50 k

Ω pull-down resistors. When the

inputs are either unconnected or at the same potential the

outputs will go low.

When used in single-ended operation the apparent input

threshold of the true inputs is 20 mV to 40 mV higher (posi-

tive) than the threshold of the complementary inputs. The
