description

The SN54BCT541 and SN74BCT541A octal buffers and line drivers are ideal for driving bus lines or buffering memory-address registers. The devices feature 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 ) input is high, all eight outputs are in the high-impedance state.

The SN54BCT541 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74BCT541A is characterized for operation from 0°C to 70°C.
