74F540 鈥?74F541
Octal Buffer/Line Driver with 3-STATE Outputs
General Description
The 74F540 and 74F541 are similar in function to the
74F240 and 74F244 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 micro-
processors, allowing ease of layout and greater PC board
density.
