T73LVP23
Dual
LVPECL to TTL/CMOS Translator
GENERAL
DESCRIPTION
The TLSI T73LVP23 is a general purpose dual differential
LVPECL (Positive ECL) to TTL/CMOS translator operating
from a single 3.3V supply. An 8-pin SOIC package makes it
ideal for applications that require the translation of a clock
and a data signal.
The T73LVP23 is available in only the ECL 100K
standard. Since there are no LVPECL outputs or an
external VBB reference, it does not require both ECL
standard versions..

NOTE 1 VBB
When single-ended cap coupled, VBB output is tied to the D input and D is driven for anon-inverting buffer, or VBB
output is tied to the D input and D is driven for an inverting buffer. When cap coupled differentially, VBB output is
connected through a resistor to each input pin. If used, the VBB pin should be bypassed to VCC via a 0.01 _F
capacitor. For a single-ended direct connection use an external voltage reference source such as a resistor divider.
Do not use VBB for a single-ended direct connection or port to another device
