Fairchild DM74LS365A Hex 3-state buffer/bus driver Datasheet

Revised March 2000
DM74LS365A
Hex 3-STATE Buffer/Bus Driver
General Description
This device contains six independent gates each of which
performs a non-inverting buffer function. The outputs have
the 3-STATE feature. When enabled, the outputs exhibit
the low impedance characteristics of a standard LS output
with additional drive capability to permit the driving of bus
lines without external resistors. When disabled, both the
output transistors are turned OFF presenting a high-impedance state to the bus line. Thus the output will act neither
as a significant load nor as a driver. To minimize the possibility that two outputs will attempt to take a common bus to
opposite logic levels, the disable time is shorter than the
enable time of the outputs.

Absolute Maximum Ratings(Note 1)
Supply Voltage
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.
