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.


Description

The SN54BCT540 and SN74BCT540A octal buffers and line drivers are ideal for driving bus lines or buffer memory-address registers. The SN54BCT540 and SN74BCT540A feature inputs and outputs on opposite sides of the package that facilitate printed-circuit-board layout.


The 3-state control gate of SN54BCT540 and SN74BCT540A is a 2-input AND gate with active-low inputs so that if either output-enable (OE1 or OE2) input is high, all corresponding outputs are in the high-impedance state.


The SN54BCT540 is characterized for operation over the full military temperature range of 55°C to 125°C. The SN74BCT540A is characterized for operation from 0°C to 70°C.
