Features ICC and IOZ reduced by 50% TRI-STATE inverting outputs Inputs and outputs opposite side of package, allowing easier interface to microprocessors Output source/sink 24 mA Standard Military Drawing 54AC540: 5962-8769501 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.
