INDUSTRIAL TEMPERATURE RANGE
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.
