T73LVP21
LVPECL to TTL/CMOS Translator
GENERAL
DESCRIPTION
The TLSI T73LVP21 is a general purpose differential
LVPECL (Positive ECL) to TTL/CMOS translator operating
from a single 3.3V supply. Both small outline 6-pin SOT
and 8-pin SOIC packages make it ideal for applications
which require the translation of a clock and a data signal.
The T73LVP21can be used in either a differential or single-end
input mode by use the VBB pin see note 1
.

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
