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

(OE1 or OE2) 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.
