IDT74FCT540AT/CT

FAST CMOS OCTAL

BUFFER/LINE DRIVER

DESCRIPTION:

The IDT octal buffer/line driver is built using an advanced dual metal

CMOS technology. The FCT540T is similar in function to the FCT240T,

except that the inputs and outputs 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.
