Description

The DP8308 is a high speed Schottky 8-bit TRI-STATE bidirectional transceiver designed to provide bidirectional drive for bus oriented microprocessor and digital communications systems. DP8308 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, DP8308 features glitch-free power up/down on the B port preventing erroneous glitches on the system bus in power up or down.

DP8308 is featured with Transmit (T) and Receive (R) control inputs.
