DP8308 8-Bit TRI-STATE
Bidirectional Transceiver (Non-Inverting)
General Description
The DP8308 is a high speed Schottky 8-bit TRI-STATE bidi-
rectional 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 com-
patibility with MOS CMOS and other technologies that
have a higher threshold and less drive capabilities In addi-
tion 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 8-bit bidirectional data flow reduces system package
count

CMOS
Y 48 mA 300 pF bus drive capability
Y Pinouts simplify system interconnections
Y Independent T and R controls for versatility
Y Compact 20-pin dual-in-line package
Y Bus port glitch free power up down
