DM54LS366A/DM74LS366A
Hex TRI-STATE Inverting Buffer
É
General Description
This device contains six independent gates each of which
performs an inverting buffer function. The outputs have the
TRI-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 signifi-
cant 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)
If Military/Aerospace specified devices are required,
please contact the National Semiconductor Sales
Office/Distributors for availability and specifications.
Note: The ‘‘Absolute Maximum Ratings’’ are those values
beyond which the safety of the device cannot be guaran-
teed. The device should not be operated at these limits. The
parametric values defined in the ‘‘Electrical Characteristics’’
table are not guaranteed at the absolute maximum ratings.
The ‘‘Recommended Operating Conditions’’ table will define
the conditions for actual device operation.
