DESCRIPTION
The SN65LVEL11 is a fully differential 1:2 ECL fanout
buffer. The device includes circuitry to maintain a
known logic level when inputs are in open condition.
The SN65LVEL11 is functionally equivalent to
SN65EL11 with improved performance. The
SN65LVEL11 is housed in an industry standard
SOIC-8 package and is also available in the
TSSOP-8 package option.
