8286/8287
OCTAL BUS TRANSCEIVER
• Data
Bus
Buffer Driver for iAPX 86,88,
MCS·80™, MCS·8S™, and
MCS·48™
Families
• High Output Drive Capability for
Driving System Data Bus
• Fully Parallel 8·Bit Transceivers
• 3·State Outputs
• 20·Pin Package with 0.3" Center
• No Output Low Noise when Entering
or Leaving High Impedance State
The
8286
and 8287 are 8-bit bipolar transceivers with 3-state outputs. The
8287
inverts the input data at its outputs
while the
8286
does not. Thus, a wide variety
of
applications for buffering in microcomputer systems can
be
met.
