54F74F540

Octal BufferLine 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 Dia-

grams) This pinout arrangement makes these devices es-

pecially useful as output ports for microprocessors allowing

ease of layout and greater PC board density
