Product Summary

This family include DP8303AN of high speed Schottky 8-bit TRI-STATE bidirec-tional transceivers are designed to provide bidirectional drive for bus oriented microprocessor and digital communications systems. They are all 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, they including DP8303AN all feature glitch-free power up/down on the B port preventing erroneous glitches on the system bus in power up or down.

Parametrics

The absolute maximum ratings of DP8303AN are
(1)Supply Voltage: 7V;
(2)Input Voltage: 5.5V;
(3)Output Voltage: 5.5V;

Features

The features of DP8303AN can be summarized as
(1)8-bit directional data flow reduces system package count;
(2)Bidirectional TRI-STATE inputs/outputs interface with bus oriented systems;
(3)PNP inputs reduce input loading;
(4)Output high voltage interfaces with TTL, MOS, and CMOS;
(5)48 mA/300 pF bus drive capability;
(6)Pinouts simplify system interconnections;
(7)Transmit/Receive and chip disable simplify control logic;
(8)Compact 20-pin dual-in-line package;
(9)Bus port glitch free power up/down;
