The SY10/100ELT20V is a single TTL-to-differential
PECL translator. Because PECL (Positive ECL) levels
are used, either +5V or +3.3V and ground are required.
The small outline 8-lead SOIC package and low skew
single gate design make the ELT20V ideal for applications
that require the translation of a clock or data signal where
minimal space, low power, and low cost are critical.
The ELT20V is available in both ECL standards: the
10ELT is compatible with positive ECL 10H logic levels,
while the 100ELT is compatible with positive ECL 100K
logic levels.

Note 1.
Permanent device damage may occur if ABSOLUTE MAXIMUM RATINGS are exceeded. This is a stress rating only and functional operation
is not implied at conditions other than those detailed in the operational sections of this data sheet. Exposure to ABSOLUTE MAXIMUM
RATlNG conditions for extended periods may affect device reliability.
Note 2.
These values are for VCC = 5.0V. Level Specifications will vary 1:1 with VCC.
Note 3.
Input Rise Time < 1.0ns.
Note 4.
Guaranteed by design. Not tested in production.
