TTL to Differential PECL

Translator

The MC10ELT/100ELT20 is a TTL to differential PECL translator.

Because PECL (Positive ECL) levels are used only +5V and ground are

required. The small outline 8-lead SOIC package and the single gate of

the ELT20 makes it ideal for those applications where space,

performance and low power are at a premium. Because the mature

MOSAIC 1.5 process is used, low cost can be added to the list of

features.

The ELT20 is available in both ECL standards: the 10ELT is compatible

with positive MECL 10H logic levels while the 100ELT is compatible with

positive ECL 100K logic levels.

• 1.5ns Typical Propagation Delay

• Differential PECL Outputs

• Small Outline SOIC Package

• PNP TTL Inputs for Minimal Loading

• Flow Through Pinouts
