The
821618226
Is a 4-blt bidirectional bus driver/receiver_ All Inputs are low power
TIL
compatible. For driving MOS. the
DO
outputs provide a high 3.65V
"OH,
and for high capacitance terminated bus structures, the
DB
outputs provide a
high 50 mA
10L
capability. A non-Inverting (8216) and
an
inverting (8226) are available
to
meet a wide variety
of
applica-
tions
for
buffering In microcomputer systems.
