description
These octal buffers and line drivers are designed
specifically to improve both the performance and
density of 3-state memory address drivers, clock
drivers, and bus-oriented receivers and
transmitters. Taken together with the BCT240
and BCT244, these devices provide the choice of
selected combinations of inverting and
noninverting outputs, symmetrical OE (active-low
output-enable) inputs, and complementary OE
and OE inputs.
The SN54BCT241 is characterized for operation
over the full military temperature range of − 55°C
to 125°C. The SN74BCT241 is characterized for
operation from 0°C to 70°C.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
