74F2243
Quad Bus Transceiver
with 25
Series Resistors in the Outputs
General Description
The 74F2243 is a quad bus transmitter/receiver which can
be used for 4-line asynchronous 2-way data communica-
tions between data busses. It is designed to drive the
capacitive inputs of MOS memory drivers, address drivers,
clock drivers, and bus-oriented transmitters/receivers.
The 25
series resistors in the outputs reduce ringing and
eliminate the need for external resistors.
