FEATURES
DESCRIPTION
■ 3.3V and 5V power supply options
■ 300ps typical propagation delay
■ Low power
The SY10/100ELT20V is a single TTL-to-differential
PECL translators. 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.
■ Differential PECL output
■ PNP TTL input for minimal loading
■ Flow-through pinouts
■ Available in 8-pin SOIC package
