ONSEMI MC10ELT24

SEMICONDUCTOR TECHNICAL DATA
The MC10ELT/100ELT24 is a TTL to differential ECL translator.
Because ECL levels are used a +5V, -5.2V (or -4.5V) and ground are
required. The small outline 8-lead SOIC package and the single gate of
the ELT24 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 ELT24 is available in both ECL standards: the 10ELT is compatible
with MECL 10H logic levels while the 100ELT is compatible with ECL
100K logic levels.
