FEATURES

3.3V power supply

2.0ns typical propagation delay

Low power

Differential LVPECL inputs

24mA TTL outputs

Flow-through pinouts

Available in 8-pin SOIC package

3.3V DIFFERENTIAL

LVPECL-to-LVTTL

TRANSLATOR

to-LVTTL translators using a single +3.3V power supply.

Because LVPECL (Low Voltage Positive ECL) levels are

used, only +3.3V and ground are required. The small

outline 8-lead SOIC package and low skew single gate

design make the ELT21L ideal for applications that require

the translation of a clock or data signal where minimal

space, low power, and low cost are critical.

ground. This condition will force the Q output low to

provide added stability.

10ELT is compatible with positive ECL 10H logic levels,

while the 100ELT is compatible with positive ECL 100K

logic levels.
