Product Summary

The MC100ELT28DR2 is a differential PECL to TTL translator and a TTL to differential PECL translator in a single package. Because PECL (Positive ECL) levels are used, only +5 V and ground are required. The small outline 8-lead package and the dual translation design of the ELT28 makes the MC100ELT28DR2 ideal for applications which are sending and receiving signals across a backplane. The 100 Series contains temperature compensation.
