Product Summary
The DP7304BJ is a high speed Schottky 8-bit TRI-STATE bidirectional transceiver designed to provide bidirectional drive for bus oriented microprocessor and digi?tal communications systems. The DP7304BJ is 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 (VQH) level allow compatibility with MOS, CMOS, and other technologies that have a higher threshold and less drive capabilities. In addition, the DP7304BJ features glitch-free power up/down on the B port preventing erroneous glitches on the system bus in power up or down. The DP7304BJ is featured with Transmit/Receive (T/R) and Chip Disable (CD) inputs to simplify control logic.
