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.
