54AC540
Octal Buffer/Line Driver with TRI-STATE® Outputs
General Description
The 'AC540 is an octal buffer/line drivers designed to be employed as memory and address drivers, clock drivers and bus oriented transmitter/receivers.
These devices are similar in function to the 'AC240 while providing flow-through architecture (inputs on opposite side from outputs). This pinout arrangement makes these devices especially useful as output ports for microprocessors, allowing ease of layout and greater PC board density.
Features
nICC and IOZ reduced by 50%
nTRI-STATE inverting outputs
nInputs and outputs opposite side of package, allowing easier interface to microprocessors
nOutput source/sink 24 mA
nStandard Military Drawing 54AC540: 5962-8769501
