DM54367 Hex TRI-STATE Buffers

DM54367 Hex TRI-STATEÉBuffers

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-imped­ance 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 oppo­site logic levels, the disable time is shorter than the enable
time of the outputs.

Note:

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’’
table are not guaranteed at the absolute maximum ratings.
The ‘‘Recommended Operating Conditions’’ table will define
the conditions for actual device operation.
