ONSEMI MC10ELT21

SEMICONDUCTOR TECHNICAL DATA
The MC10ELT/100ELT21 is a differential PECL to TTL translator.
Because PECL (Positive ECL) levels are used only +5V and ground are
required. The small outline 8-lead SOIC package and the single gate of
the ELT21 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 VBB output allows the ELT21 to also be used in a single-ended
input mode. In this mode the VBB output is tied to the IN input for a
non-inverting buffer or the IN input for an inverting buffer. If used the VBB
pin should be bypassed to ground via a 0.01µF capacitor.
The ELT21 is available in both ECL standards: the 10ELT is compatible
with positive MECL 10H logic levels while the 100ELT is compatible with
positive ECL 100K logic levels.
