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 Features Y Y TRI-STATE outputs drive bus lines Inputs and outputs opposite side of package allowing easier interface to microprocessors Commercial 74F540PC Military Package Number N20A Package Description 20-Lead (0 300 Wide) Molded Dual-In-Line 20-Lead Ceramic Dual-In-Line 20-Lead (0 300
