Differential ECL to TTL
Translator
The MC10ELT/100ELT25 is a 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.
The VBB output allows the EL T25 to also be used in a single-ended
input mode. In this mode the VBB output is tied to the IN
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 ELT25 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. For further information
regarding modeling, refer to AN1596/D “ECLinPS Lite Translator
ELT Family SPICE I/O Model Kit”.
