General Description
The ’F540and ’F541are similarin functiontothe ’F240and
’F244 respectively, except thatthe inputs and outputsare opposite sidesofthe package (see Connection Dia-
grams). This pinout arrangement makes these deviceses-
pecially usefulas output portsfor microprocessors, allowing
easeof layoutand greaterPC board density.
Features TRI-STATE outputs drivebus lines Inputs and outputs opposite sideof package, allowing
