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 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
Features
Y TRI-STATE outputs drive bus lines
Y Inputs and outputs opposite side of package allowing
easier interface to microprocessors
