DUAL DIFFERENTIAL
PECL-to-TTL
TRANSLATOR
FEATURES
■ 3.0ns typical propagation delay
■ <500ps typical output-to-output skew
■ Differential PECL inputs
Precision Edge™
DESCRIPTION
■ 24mA TTL outputs
■ Flow-through pinouts
The SY10/100ELT23 are dual differential PECL-to-TTL
translators. Because PECL (Positive ECL) levels are
used, only +5V and ground are required. The small outline
8-lead SOIC package and the low skew dual gate design
of the ELT23 makes it ideal for applications which require
the translation of a clock and a data signal.
■ Available in 8-pin SOIC package
The ELT23 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.
