Octal Buffer/Line Driver with 3-STATE Outputs
74AC540 Octal Buffer/Line Driver with 3-STATE Outputs November 1988 Revised March 2005 74AC540 Octal Buffer/Line Driver with 3-STATE Outputs General Description Features The AC540 is an octal buffer/line drivers designed to beI and I reduced by 50% CC OZ employed as memory and address drivers, clock drivers 3-STATE inverting outputs and bus oriented transmitter/receivers. Inputs and outputs opposite side of package, allowing These devices are similar in function to the AC240 while easier interface to microprocessors providing flow-through architecture (inputs on opposite side Output source/sink 24 mA from outputs). This pinout arrangement makes these devices especially useful as output ports for microproces- sors, allowing ease of layout and greater PC board density.
