Overview
DP8308 8-Bit TRI-STATE Bidirectional Transceiver (Non-Inverting) February 1996 DP8308 8-Bit TRI-STATE Bidirectional Transceiver (Non-Inverting) General 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 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 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 free power up down Logic and Connection Diagrams Dual-In-Line Package TL F 8795 – 1 Logic Table Control Inputs Transmit 1 0 1 0 Receive 0 1 1 0 Resulting Conditions A Port OUT IN TRI-STATE B Port IN OUT TRI-STATE TL F 8795 – 2 Top View Order Number DP8308N See NS Package Number N20A Both Active This is not an intended logic condition and may cause oscillations TRI-STATE is a registered trademark of National Semiconductor Corp C1996 National Semiconductor Corporation TL F 8795 RRD-B30M36 Printed in U S A http www national com Absolute Maximum Ratings (Note 1) If Military Aerospace specified devices are required please contact the National Semiconductor Sales Office Distributors for availability and specifications Supply Voltage Input V...
