. To reduce crosstalk, each output has its own
respective ground connection. Transition times were
designed to be longer than on other F100K devices. The
driver itself performs the positive logic AND of a data input
(D

) and the OR of two select inputs (E and either DE

,
DE

, or DE

).
Enabling of data is possible in multiples of two, i.e., 2, 4 or
all 6 paths. All inputs have 50 k

pull-down resistors.
The output voltage LOW level is designed to be more neg-
ative than normal ECL outputs (cut off state). This allows
an emitter-follower output transistor to turn OFF when the
termination supply is

2.0V and thus present a high imped-
ance to the data bus.
