The DP8307A is a high speed Schottky 8-bit TRI-STATE bidirectional transceiver designed to provide bidirectional drive for bus oriented microprocessor and digital communications systems It is capable of sinking 16 mA on the A ports and 48 mA on the B ports (bus ports) PNP inputs for low input current and an increased output high (VOH) level allow compatibility with MOS CMOS and other technologies that have a higher threshold and less drive capabilities In addition it features glitch-free power up down on the B port preventing erroneous glitches on the system bus in power up or down
