54F 74F540 54F 74F541 Octal Buffer Line Driver with TRI-STATE Outputs
May 1995
54F 74F540 54F 74F541 Octal Buffer Line Driver with TRI-STATE Outputs
General Description
The 'F540 and 'F541 are similar in function to the 'F240 and 'F244 respectively except that the inputs and outputs are on opposite sides of the package (see Connection Diagrams) This pinout arrangement makes these devices especially useful as output ports for microprocessors allowing ease of layout and greater PC board density
