DESCRIPTION:

The IDT octal buffer/line drivers are built using an advanced

dual metal CMOS technology. The IDT54/74FCT240/A/C,

IDT54/74FCT241/A/C and IDT54/74FCT244/A/C are designed

to be employed as memory and address drivers, clock drivers

and bus-oriented transmitter/receivers which provide improved

board density.

The IDT54/74FCT540/A/C and IDT54/74FCT541/A/C are

similar in function to the IDT54/74FCT240/A/C and IDT54/

74FCT244/A/C, respectively, except that the inputs and out-

puts are on opposite sides of the package. This pinout

arrangement makes these devices especially useful as output

ports for microprocessors and as backplane drivers, allowing

ease of layout and greater board density.
