Octal 3-STATE Buffer/Line Driver/Line Receiver
General Description
These buffers/line drivers are designed to improve both the
performance and PC board density of 3-STATE buffers/
drivers employed as memory-address drivers, clock driv-
ers, and bus-oriented transmitters/receivers. Featuring
400 mV of hysteresis at each low current PNP data line
input, they provide improved noise rejection and high
fanout outputs and can be used to drive terminated lines
down to 133
.
Features
