NEe Microcomputers, Inc. NEe JLPB8286 u.PBS-287 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 Cap.
