DM54367 Hex TRI-STATE Buffers

É

General Description

This device contains six independent gates each of which

performs a non-inverting buffer function. The outputs have

the TRI-STATE feature. When enabled, the outputs exhibit

the low impedance characteristics of a standard TTL 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-imped-

ance state to the bus line. Thus the output will act neither as

a signficant load nor as a driver. To minimize the possibility

that two outputs will attempt to take a common bus to oppo-

site 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.
