MC10ELT20, MC100ELT20
5V TTL to Differential PECL
Translator
Description
The MC10ELT/100ELT20 is a 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 single gate of
the ELT20 makes it ideal for those applications where space,
performance, and low power are at a premium.
The 100 Series contains temperature compensation.
