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,

exceptthattheinputsandoutputsareonoppositesidesofthepackage. 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.
