8-BIT BUS TRANSCEIVER
DESCRIPTION
The 8286 and 8287 are octal bus transceivers used for buffering microprocessor
bus lines. Being bi-directional, they are ideal for buffering the data bus lines on
8 or 16 bit microprocessors. Each B output is capable of driving 32 mA low or 5 mA
high.
F EATU RES
• Data Bus Buffer Driver for IlCOM·8 (8080, 8085A, 780) and IlCOM-16 (8086)
families
• Low Input Load Current --- 0.2 mA max.
• High Output Drive Capability for Driving System Data Bus
• Tri·State Outputs
• 20 Pin Package with Fully Parallel 8·Bit Transceivers
