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 out-
puts, and can be used to drive terminated lines down to
133.
Features
s 3-STATE outputs drive bus lines directly
s PNP inputs reduce DC loading on bus lines
s Hysteresis at data inputs improves noise margins
s Typical IOL (sink current)
64 mA
s Typical IOH (source current) 15 mA
s Typical propagation delay times
Inverting
4.5 ns
Noninverting 6 ns
s Typical enable/disable times 9 ns
s Typical power dissipation (enabled)
Inverting
450 mW
Noninverting 538 mW

Note 1: The “Absolute Maximum Ratings” are those values beyond which
the safety of the device cannot be guaranteed. The device should not be
operated at these limits. The parametric values defined in the Electrical
Characteristics tables are not guaranteed at the absolute maximum ratings.
The “Recommended Operating Conditions” table will define the conditions
for actual device operation.
