ON MC10ELT22DTG 5.0 v dual ttl to differential pecl translator Datasheet

MC10ELT22, MC100ELT22
5.0 V Dual TTL to Differential
PECL Translator
The MC10ELT/100ELT22 is a dual TTL to differential PECL
translator. Because PECL (Positive ECL) levels are used only +5 V
and ground are required. The small outline 8-lead 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.
