description

The SN54BCT540 and SN74BCT540A octal

buffers and line drivers are ideal for driving bus

lines or buffer memory-address registers. The

devices feature inputs and outputs on opposite

sides of the package that 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

(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.
