DESCRIPTION
The SY100ELT25 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 performance,
space and low power are at a premium.
The VBB output allows the ELT25 to also be used in a
single-ended input mode. In this mode the VBB output is
tied to the D input for a non-inverting buffer or the D
input for an inverting buffer. If used the VBB pin should
be bypassed to ground via a 0.01µF capacitor.
