Dual	TTL to Differential	MC10ELT22
PECL	Translator	MC100ELT22

The MC10ELT/100ELT22 is a dual 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 low skew, dual gate design of the ELT22 makes it ideal for applications which require the translation of a clock and a data signal. Because the mature MOSAIC 1.5 process is used, low cost can be added to the list of features.

The ELT22 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

•<300ps Typical Output to Output Skew

•Differential PECL Outputs

•Small Outline SOIC Package

•PNP TTL Inputs for Minimal Loading

•Flow Through Pinouts
