DP8308 8-Bit TRI-STATE Bidirectional Transceiver

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 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 compatibilit.

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 Features Y Y Y Y Y Y Y Y Y 8-bit bidirectional data flow reduces system package count Bidirectional TRI-STATE inputs outputs interface with bus oriented systems PNP inputs reduce input loading Output high voltage interfaces with TTL MOS and CMOS 48 mA 300 pF bus drive capability Pinouts simplify system interconnections Independent T and R controls for versatility Compact 20-pin dual-in-line package Bus port glitch fr.
