FEATURES
SY100EPT23L
DESCRIPTION
■
■
■
■
■
■
■
3.3V power supply
1.9ns typical propagation delay
Maximum frequency > 275MHz
Differential LVPECL inputs
24mA LVTTL outputs
Flow-through pinouts
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 SY100EPT23L is a dual differential LVPECL-toLVTTL 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.
The EPT23L is available in only the ECL 100K
standard. Since there are no LVPECL outputs or an
external VBB reference, the EPT23L does not require
both ECL standard versions. The inputs can accept 10K
voltage levels and any standard differential LVPECL input
referenced from a VCC of +3.3V

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.
