description
The ′F541 octal buffer/line driver is ideal for driving
bus lines or buffering memory address registers.
The device features inputs and outputs on
opposite sides of the package to facilitate
printed-circuit-board layout.
The 3-state control gate is a 2-input AND gate with
active-low inputs so that if either output enable
or OE2) input is high, all eight outputs are in
(OE1
the high-impedance state.
The SN54F541 is characterized for operation over
the full military temperature range of –55°C to
125°C. The SN74F251 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 voltage ratings may be exceeded provided the input current ratings are observed.
