3.3V DUAL DIFFERENTIAL
LVPECL-to-LVTTL TRANSLATOR
ECL Pro™
SY100EPT23L
FEATURES
■ 3.3V power supply
■ 1.9ns typical propagation delay
■ Maximum frequency > 275MHz
■ Differential LVPECL inputs
■ 24mA LVTTL outputs
ECL Pro™
DESCRIPTION
■ Flow-through pinouts
The SY100EPT23L is a dual differential LVPECL-to-
LVTTL translator. Because LVPECL (Low Voltage Positive
ECL) levels are used, only +3.3V and ground are required.
The tiny 8-pin MSOP and dual-gate design of the EPT23L
makes it ideal for applications which require the
translation of a clock and data signal.
■ Internal input resistors: pulldown on D, pulldown
and pullup on /D
■ Q output will default LOW with inputs open or at
Ground
■ Available in 8-pin MSOP and SOIC packages
The EPT23L is available in only the ECL 100K
standard. Since there are no LVPECL outputs or an
external V
reference, the EPT23L does not require
BB
both ECL standard versions. The inputs can accept 10K
voltage levels and any standard differential LVPECL input
referenced from a V
of +3.3V
