SEMICONDUCTOR TECHNICAL DATA
Differential ECL to TTL
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 ELT25 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.
input mode. In this mode the V BB output is tied to the IN input for a
non-inverting buffer or the IN input for an inverting buffer. If used the V BB
pin should be bypassed to ground via a 0.01 F capacitor.

The MC10ELT/100ELT25 is a differential ECL to TTL translator.
The V BB output allows the ELT25 to also be used in a single-ended
The ELT25 is available in both ECL standards: the 10ELT is compatible
