Revised January 2003
General Description
The 100EL11 is a 5V 1:2 differential fan out buffer. One differential input signa l is f anned out to two ide ntical differential outputs. By supp l ying a con stan t r eference level to one
input pin a single ended input condition is created.
With inputs open or b oth inputs at V
outputs default LOW and Q
The 100 series is temperature compensated.
outputs default HIGH.
