description
These octal buffers and line drivers are designed
specifically to improve the performance and
density of 3-state memory address drivers, clock
drivers, and bus-oriented receivers and
transmitters.
The ’ACT241 are organized as two 4-bit
buffers/drivers with separate complementary
output-enable (1OE
is low or 2OE is high, the device passes
noninverted data from the A inputs to the
Y outputs. When 1OE
outputs are in the high-impedance state.
The SN54ACT241 is characterized for operation
over the full military temperature range of –55°C
to 125°C. The SN74ACT241 is characterized for
operation from –40°C to 85°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.
NOTES: 1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
2. The maximum package power dissipation is calculated using a junction temperature of 150°C and a board trace length of 750 mils,
except for the N package, which has a trace length of zero.
